Sunset on a Day of Data

??????????????????????????????????????????????????????????????  ?????????????????????? ??????????????????????????????? ??????????????????????The day began with a dark run for 5 of us and a sunrise swim for 4 of the runners plus 2.  After paddling around in the blue ocean watching the sky change colors convinced all of us that everyday should begin this way.  After a breakfast of pancakes we grabbed our gear and hiked down the muddy road to Great Lameshur for our first permanent transect data collection.  The fish team (Renee, Felicity, Caleb and Sam) needed to swim 6 thirty meter transects identifying and sizing all fish within those transects.  The coral team (Natasha, Ashely, Jentry, and Mae) needed to identify and size all coral that was within a meter of either side of their 10 meter transect lines.  Finally the benthic team (Brit and Natalie) needed to categorize what was under each 10 cm mark on a 10 m transect line.  The coral and benthic team spent lots of time diving!

Our sampling site was probably 1/3rd of a mile from shore – so after a long rather cool swim we were finally able to start our data collection.  It was a challenge particularly after more than an hour and a half in the water, but all were willing in the name of science!  We pulled out on a small pebble beach to warm up before the long swim back to shore – those warm rocks were scrumptious!  We are back in camp and grabbed a moment when the internet was functional to post some pics.  (Above sunrise swim club, off to collect data, butter hamlet, Felicity and those rocks, Hawksbill sea turtle).

We are resting a bit and plan to hike to Ramshead for the sunset and then a night snorkel in Blue Cobblestone.  Hope to collect some tourist data at Saltpond along the way….will add more if we can!


Working out the Kinks

???????????????????????????????We spent the day working out the kinks in our research Plan.  Discovered that waterproof paper wasn’t so waterproof and that laying down transect lines presented more challenges than we imagined!  Tomorrow we collect our first round of data.

The internet here is incredibly slow and often unavailable….we will do our best to keep blogging….but don’t worry if we aren’t active on this site!  Rest assured that we are active and doing well!??????????????????????  Above is a white-spotted file fish – a new species for us all!



We left in 8 degree temps and arrived in St John to 80!  Quite a welcome change for us all.  The day was a long one – starting at 5:30 a.m. ride to airport and ending with an 8 p.m. arrival at VIERS.  Everyone felt as though we were returning home again!  We were all very exhausted and headed to bed by 9:30 p.m.  Can’t wait to put our toes in that Caribbean ocean!


Beautiful rainbows greeted us at the airport!  We are

Home Again After a long long day of travel!


It takes a group to construct a Transect Line….the Adventure Continues….2015 in the Caribbean

??????????????????????????????? ???????????????????????????????

Half of Caribbean Crew of 2014 is back and dreaming of blue oceans and sunny skies.  We are returning to St. John in the hopes of gathering some baseline data on coral, fish diversity and the benthos at a couple of sites (Great Lameshur and Leinster Bay).  We’ve been building the equipment we will need for sampling – including these 10 m transect lines.  We will be describing our continuing adventures and research on this site and hope you will join us on our journey.


What did we Learn?

group shot leaving viers small

Our last day on island was one of moving and reflecting….We left VIERS at 8 a.m. and arrived back at Hollins at midnight.  Plenty of time to reflect on our action-packed Journey.  In only 10 days on island we: snorkeled in the day at 17 different sites; did two night snorkels; cleaned up 4 beaches and removed over 205 pounds of debris (mostly plastic); hiked at night,  in silence, without flashlights, on 4 different occasions; watched at least two sunrises; visited 6 sugar plantation ruins and wrestled with the pain of the sugar-coating of the brutality of slavery which shapes this landscape and its people;  laughed; sang; danced; ran; swam; and collected data to find out answers to our research questions.  While we were each one of 20, we came to value that as a group we were even greater than the sum of our own individual experiences.  It was difficult to realize that our group would soon be dispersing.

Snow greeted us on our return providing the perfect backdrop for three intense days of data analysis and the development of research posters which will be presented in April at the 57th Annual Hollins Science Seminar.  Below are summaries of our findings:

The Brainiacs:  Ashley, Mae and Natasha

We were interested in the impact of water pollution on coral health. So we compared brain coral health in watersheds with varying levels of human development on the island of St. John, USVI.  Using 10 meter circular transects, the number, size, and relative health of brain coral was assessed in 9 different watersheds – a total of 27 transect surveys were conducted. Analyzing the data collected, we found that there was a significant increase in the density of coral in watersheds with low disturbance  when compared to those with higher levels of disturbance. Larger sample sizes and more sites in higher impacted areas could shed more light on this issue.  We are definitely ready to go back next January and dig a bit more into this issue!

Queen Conch Fritters – Sam Cline

sam with conchIn shallow water environments in the Caribbean, the Queen Conch (Strombus gigas) mollusc plays an important biological role as an algal grazer and detritovore.  Because it is an important fisheries species as well, its populations have declined (at one inshore site off the island of St. John, USVI, the Queen Conch population declined by 97% over a 5 year study period 1986-1991).  As a pilot study, I was interested in determining the current population density, size, and age class of the Queen Conch in sea grass beds  of St. John, USVI. Shell length, lip thickness, depth, location, and signs of harvest were recorded during each ten minute swim survey. I found a total of 32 live conch were found (21 juvenile, 11 adult). No empty conch shells had indication of illegal harvesting.  There was a significant positive correlation between shell length and depth at which conch shells were found. While these findings suggest an overall decline in Queen Conch population compared to historic population estimates, the 1.9:1 juvenile :adult ratio suggests that there has been some recent reproductive success and that the population may be able to recover.  Additional survey sites and survey replication over time will provide important information for Queen Conch population size and may help guide regulation patterns.

Getting to the Point:  Urchin Populations and Coral Health – Natalie and Brittany

Natalie and Brittany UrchinsThe health of coral reefs are dependent on organisms that graze algae such as the long-spined sea urchin Diadema antillarum.   According to Lessios et al. (1984), the condition of USVI coral reefs was significantly impacted by a tremendous die-off of the long-spined sea urchin in the 1980s. We were interested in surveying the population of long-spined urchins and in correlating their population density to coral population patterns.  We carried out 20 minute swimming surveys of long-spined urchin numbers in four bays surrounding St. John USVI and found that there was a significant relationship between urchin population number and the number of brain coral classified in a  “small”  size class.  This positive relationship with urchin density and young brain coral suggest that the population rebound of urchins may benefit the regeneration of brain coral on reefs.

Stripes and Patterns – Felicity and Brenna

Felicity and Brenna pic schoolmasterThe Lutjanus apodus (Schoolmaster) fish experiences metachrosis prompted by a variety of external and internal factors including change in background color, habitat, excitement, courtship, feeding and threat of predation. We were interested to see if we could detect a relationship with color change in this species with its activity level and habitat.  We collected data in three different habitat types: Mangrove, reef and grassbed. At each site we would swim from one end of the bay to the other and note the number of schoolmasters seen, striping patterns, activity level and whether or not they were in a structure. We found the highest population density of Schoolmasters in the mangrove and grassbed habitats but surveyed more reef habitats. Most schoolmasters detected were striped, however, we found no relationship between striping patterns and activity level and habitat. We concluded that further research and a larger sample size are necessary to achieve more definitive results.

Boulder Bunch – Rory, Andi, and Lucy

boulder bunch brain coralMajor coral bleaching events in the Caribbean in 2005 and 2010 has caused significant mortality of coral in reefs surrounding St. John.  We were interested in assessing the population patterns of Grooved Boulder Brain coral (Colpophyllia natans) in mangroves, coral reefs and in colonized pavement habitats. We predicted that coral in shallow mangrove habitats would be more susceptible to temperature oscillation and might have more health issues.  Using 45 minute swimming surveys, we estimated brain coral health and size in these three environments and found no correlation between brain coral health and habitat. However, 61% of the brain coral we found was classified as small and in good health indicating that there is recruitment of this species in all surveyed areas. These findings suggest that boulder brain coral may be recovering from the most recent bleaching events. More research should be conducted to confirm these findings.

Sensitive Feathers – Amy

amy wormI was very interested in studying the behavior of a marine species and settled my research question on the magnificent feather duster, Sabellastarte magnifica, a species of stationary marine worm which lives inside self-constructed tubes exposing only their branchial crown exposed, for both respiration and filter feeding. When disturbed, these worms will retract in order to avoid predation.  I expected to find that magnificent feather dusters would display a lower sensitivity to disturbance in shallow waters or waters with high wave action.  In order to test this I approached feather dusters at different depths and in different water conditions and squirted water from a syringe towards their exposed crown.  I found that feather dusters in shallow and medium depths were significantly less sensitive to sea water administration than those in deeper water (ANOVA P = 0.02).  In addition, I found that worms exposed to greater natural wave action were less sensitive to sea water administration than those in calmer habitats (KW P = 0.004). These data suggest that magnificent feather dusters situated at shallower depths and in areas of higher natural wave action may be more vulnerable to predation – a finding that bears further investigation.

Lionizing shifts in Biodiversity and Abundance Patterns – Kristin

kristin lionfishLionfish are voracious predators that were first found in St. John in March of 2010. Their full impacts on coral reef health and biodiversity are not known, but studies have shown that the presence of lionfish on a reef can reduce the recruitment of native fishes by up to 80%.  For the past 3 years I have estimated fish biodiversity in 10 sites (four habitats).  At each site I conduct a 10 minute swimming survey and note species and relative abundance.  When comparing across years, mangrove habitats showed the highest rate of decline in abundance while the other 3 habitats (grassbeds, colonized bedrock and coral reefs) showed reductions that were not as dramatic.  The rates of decline in abundance of species on Coral Reefs were greater between 2012 and 2013 than between 2013 to 2014. These findings suggest that there are negative impacts to populations, however, improvement in the ability of species to recognize the lionfish as a predator or the continual effort by dedicated volunteers to keep lionfish populations in check may help to stabilize reef fish populations.

Do Tell:  Understanding Tourist Activity and Knowledge – Jentry, Suzanne, and Melissa

??????????????????????????????? Melissa and Suzanne surveyingEducated tourists often have less impact on the places they visit and often have richer experiences.  We wanted to assess the historical and environmental knowledge of tourists that were visiting St. John, USVI.  As such, we interviewed 111 people, 98% of whom were white Americans with an average age of 46.  Approximately two-thirds of the Americans were from the northeastern U.S and over 40% were able to correctly identify rainwater as the primary freshwater source on the island.  We did find that those tourists that had visited St. John more than 6 times were more likely to understand water issues relevant to the islands than those less frequent visitors.  Over half of the tourists indicated that slavery and plantations had important historical impacts on the island.  Analysis of this rich data set will continue, but these preliminary findings suggest that a significant number of tourists are unaware of important environmental and historical issues.

The Parrotheads – Sarah, Caleb, Captain Morgan, Commander Renee

caleb and sarah stoplight initialsThe status of parrotfish populations are a good indicator of coral health, as they play a key role as algae grazers in sustaining coral reef habitats. Without this grazing, algal growth may inhibit photosynthesis of  the coral’s symbiotic algae (zooxanthellae) as well as promote bacterial growth. Our project is focused on understanding the abundance and sex ratio patterns of parrotfish in different marine habitats (colonized pavement and coral reefs) in St John over a two year time period. We compared abundance patterns  between these two habitats  as well as between years and relationship to protected park waters.  Parrotfish were found to be more abundant in reef habitats and showed a decline in abundance from 2013 to 2014.  Two species which showed dramatic declines in abundance exhibited a decrease in the ratio of initial to terminal fish.  These findings suggest that there may be weak recruitment of initial parrotfish which are all female over the last year.  This finding bears further investigation as parrotfish populations are an important component in maintaining coral health.


It has been a grand learning experience – one we were privileged to lead!


How much can we do on our last day?

With the sad, certain knowledge that today was our last day, the group decided to pack in as much as possible!  If we had to go home, we would go home having experienced as much as possible.  Unfortunately the Unitarians that were sharing the field station for the night decided to sing, loudly and somewhat off key until 10 p.m. Saturday night.  We will never be able to listen to American Pie or Sound of Silence again!

Most of us arose at 5:00 for a last sunrise hike.  We were glad to have VIERS volunteers John and Pam join us for our silent walk in the moonlight and our quiet witness to the changing of the guard – moonset and sunrise!

The first hints of red in the sky were such a welcomed sight!


This sunrise was different than our first – a quiet change to red then back to gray and then a magnificent burst of color.  We could probably watch sunrises here everyday of the year and never see the same one twice!

We gathered for one last picture in the early morning rays.


And we headed back down the trail – though it was hard to leave, particularly for the seniors Sarah and Kristin!

But the beautiful color on the mountains and blue cobblestone soothed our heavy hearts on this our last day.

With a good breakfast in our bellies we headed back down the muddy road finishing our 4th beach clean-up at Little Lameshur.  We definitely left St. John a bit cleaner and have a new sense of trash!

And we found the tunnel – 15 feet below the ocean’s surface and 6 feet long….a challenge some of us decided to conquer!  Amy claims she is scared and then there she is under the water and through the tunnel!


Back to VIERS for siesta and a rousing game of spoons – such viciousness amongst good friends!



A quick dinner and then many of us headed out to snorkel the Octopus Garden in the dark for our 2nd and last night snorkel.  We started the day at 5:00 a.m. with a silent walk in the moonlight and ended it with a silent walk in the dark to Leinster bay, a 40 minute night snorkel and a quiet walk home….Exhausted we took our last drive back to VIERS – heavy hearts but also a good deal of satisfaction.  We embraced this last day to its fullest!

Notes from a Windmill

After a late night stargazing at the dock and an early morning run, we were allowed to sleep in an extra half hour (7:30!) before our pancake breakfast this morning. Covered in sunscreen and bug spray,  we soon headed out for an adventure to find the only known Baobab tree on the island of St. John- although there are rumors 0f a second. However, these trees are abundant on the island of St. Croix. This tree was located in the ruins of the Seiban Estate, as a result of seeds carried over by the enslaved Africans. This tree is thought to be magical and sacred by many African peoples. It has many names, such as the tree of life and the upside down tree.


On the way we found more sugar plantation ruins. These were the ruins of the Seiban Estate, which was created by Johan Von Seiban in 1721. It consisted of 150 acres of sugarcane, with a rum still, sugar mill, and cannons. The estate was last used as a cattle ranch when it was sold to the National Park in 1941.


After hiking back up L’Esperance trail, we hopped back into the Jeeps and drove down the road (stay to the left!) to the Cathrineberg Estate. This estate featured a well restored windmill and store warehouse. As we climbed the hill to the ruins, we were pleasantly surprised to hear the sound of tenor saxophone jazz music wafting through the air. Inside the windmill ruins was a young jazz musician named Broheim practicing his already incredible abilities. We were lucky enough to listen to him play a few songs for us as we ate our lunch before he sadly had to leave to catch the noon ferry to a nearby music festival in St. Thomas.


Inspired by this musician, the yoga-enthusiasts of our group used their “rock hard flexibility” to show us how a real headstand is done.


After learning the history of the Catherineberg Estate, we all joined together in a step dynamic photo in order to show off the architectural beauty of the storeroom arches.


During our third trip down by the Salt Pond, we crossed paths with a sociable bachelor donkey herd. Typically, young males donkeys will stay in these small bachelor groups until they are old enough to win their own herd. They were very friendly and even let a few lucky students get up close!


As the last few days on St. John near, the research teams continue to collect as much data as possible before returning to the states.


Felicity and Brenna smalldata

We returned to VIERS around 3 to allow for some time to shower, decompress, and catch up on some work before heading out to dinner at Shipwrecked! Despite some crazy light surges, everyone’s meals were amazing!

We have never been more excited for bed as we were tonight- another 4:30am morning awaits us: the sunrise hike made such an impression the first time that we have decided to go again for our last night  before we head back to chilly Virginia!

Safe sails and don’t let the donkeys bite! With love, Lucy and Ashleigh
