New dive gear washdown area
Divers and snorkelers can now enjoy the use of our new gear wash-down area at the end of a day on the water. We have 2 large tubs for wet-suits and dive BC's and fins. In addition, there are now 3 smaller tubs designated just for regulators, masks and snorkels, and camera equipment. Fresh-water showers are also available for a quick rinse-off.
Future plans include a second wash-down area to be constructed out near our wet lab.

SEAKEYS Monitoring Program at KML
By Jon Fajans, SEAKEYS Program Manager & Andrew Crowder, SEAKEYS Research Assistant
SEAKEYS, which stands for Sustained Ecological Research Related to the Management of the Florida Keys Seascape, is a research framework for scientists organized by the Florida Institute of Oceanography (FIO) in 1989, with funding from the John D. and Catherine T. MacArthur Foundation. Keys Marine Lab provides the SEAKEYS program a base for its operations. As part of SEAKEYS, FIO, in cooperation with the National Data Buoy Center (NDBC), established six enhanced Coastal Marine Automated Network (C-MAN) environmental monitoring stations. The program is now sustained annually through grants from NOAA and the EPA.

Sea Turtle nesting on Long Key
Sea turtle nesting season stretches from May 1st through October 31st here in the Keys.
The Loggerhead turtles are usually done nesting by early September but "turtlers" continue to monitor the beaches for the occasional Green or Hawksbill nest.
Long Key State Park staff and Save-a-Turtle volunteers have been monitoring the beaches of Long Key since early April. Walking the beaches each morning, they monitor the previous night's nesting activities. Only 10 Loggerhead nests were marked and monitored this year, 3 of which were within the State Park.
The eggs typically hatch 50-75 days later. The 7 nests located outside of the Park averaged 110 eggs per nest with a 54% hatching rate. Losses due to predation were around 15%, and typically are due to raccoons. The nest pictured above was flooded during the high tides and storm surges due to hurricanes (Faye, Gustav, and Ike). Turtlers usually wait at least 10 days after hatching occurs to "dig" the nests and assess hatching success. In cases of poorly-placed nests or in areas were raccoon predation is a concern, they may dig the nest sooner. Any late hatchlings left behind in the nest are scooped up, held for the day, and safely escorted to the water's edge at nightfall.
A grand total of 422 Loggerhead hatchlings left the nests from the Long Key beaches this year.

In spite of all that, reconstruction at the Lab has continued and our Marina Dorm is once again open for use. Check out the substantial new stairway and deck over-looking the marina basin!
Each building is being carefully power-washed and painted for a fresh new look - KML Green with Cream trim, blending subtlety with the palms and mangroves along the water's edge.
Can corals change their feeding mode based on environmental conditions?
The feeding ecology of corals of the
To accomplish these research goals the researchers will use a combination of field collections, field transplants, microcosm experiments, and the application of novel molecular-level biochemical and stable isotopic techniques to determine the relative importance of heterotrophic feeding versus autotrophically-derived organic matter in satisfying the nutritional requirements of the coral host. The results of this study will provide important insights into how corals may be able to adapt to declines in water quality associated with increasing coastal development and environmental change, and will therefore have direct implications for the conservation of corals in
Recent research has clearly shown that the vulnerability of corals to disturbance can be influenced by their energetic status and that the lipid reserves stored by corals may allow them to increase their resistance and resilience to stress. Moreover, the ability of corals to switch their main feeding mode, from autotrophy to heterotrophy, under marginal conditions marginal (i.e., high turbidity, sedimentation, high nutrients) can provide an adaptive mechanism for sustained growth over the short-term that may be fundamental to corals exposed to multiple stressors. The increased availability of heterotrophic energy and nutrient sources in nearshore coastal habitats has already been linked to higher coral growth, increased energy storage, and increased resilience to disturbances such as coral bleaching. These findings have led to the hypothesis that inshore habitats in the
With logistic support provided by KML’s science staff, Lirman and Teece completed coral collections at 4 reefs in the Middle Florida Keys. At each reef (2 inshore and 2 offshore reefs), small (2-4 cm2) tissue shavings were collected from 2 abundant coral species, Porites astreoides and Montastraea faveolata, using a wood chisel. Some of the samples were kept for isotopic analyses and the remaining coral chips were used for a reciprocal transplant experiment established between inshore and offshore coral reefs. In addition to the coral tissue, researchers collected water, macroalgae, zooplankton, and sediment samples to analyze the isotopic composition of benthic primary producers and potential coral food sources. All samples were initially processed at the lab facilities provided by the Keys Marine Lab at Long Key,
In June, 2008, reciprocal coral transplants were performed using tissue chips from colonies from inshore and offshore habitats to document changes in nutritional sources and lipid and protein storage as corals are transplanted to different habitats, and to evaluate the role of nutritional sources and reserves on coral growth and survivorship. Coral chips were glued to terracotta tiles and placed on PVC platforms at

reef ball mangroves at KML
Dr. Catherine Jadot - president
Ben Chisholm - project coordinator
http://www.mangrovesolutions.com
We are exploring yet another technique for planting mangroves out beyond the protection of the rip-rap. The Mangroves Solution Division is using KML as a beta test site here in the Keys.
The project:
To stabilize the seedlings (propagules) in the ocean, one proven method uses split encasement tubes driven into the sediment. This method protects against the wrack line, however, it doesn't alone promote the optimal growth of the seedling. A solution combining this wrack protection and Reef Ball technology has been developed to ensure the fastest, healthiest, and most protected growth of the mangrove tree. This solution is ideal for numerous applications including erosion efforts, enhancing aesthetical aspects of property and fertilizer runoff filtration.
Anchoring in high energy areas:
Suitable anchoring of the propagule is a common problem encountered. The Reef Ball Mangrove Planting Solution provides a steel anchor allowing a durable mooring.
Foundation Protection - Armored Cultivator Pot:
The concrete base of the device allows the propagule & roots to be protected from submerged debris. Available in a bio-degradable version, the solution has the ability to “wash away” as the mangrove matures and no longer needs assistance, leaving only a self sufficient, beautiful mangrove.
Wrack Protection - split PVC pipe:
Armored Cultivator Pot's stems will be shielded from waves, floating debris, wind, upland runoff, predation and UV, avoiding the troubles that most often cause plant failures in high energy zones
Enriched environment - fertilizer disk:
The Reef Ball Solution includes slow release fertilizer nutrients to optimize mangrove growth.
Putting it all together:
Mangrove propagules from the mangroves already on site were collected. The metal anchors were pounded into the hardbottom. The PVC wrack protectors were pounded over the stake. The armored cultivator pots were packed with peat and the bottom "sealed" with a fertilizer disk, then slid over the PVC pipe and stomped firmly into the muck on the bottom. The PVC pipes were filled with more peat to the mean high tide level and a propagule was dropped into the tube.
12 new mangroves planted at KML!
We will be watching for them to poke their noses out of the rack protectors in the next couple months as the reach for they sun.

embryonic skeletal development in brittle star
Mitch Ruzek, Ph.D. canidate
University Of South Florida (USF)
Tampa, FL
My colleagues and I in the Brian Livingston lab at USF are interested in mechanisms of control within cells that help to determine when and why certain cells take on certain fates at defined times in a developing embryo. We are specifically interested in the group of genes that is responsible for embryonic skeletal development in the brittle star Ophiocoma wendtii that is common in the Florida Keys. While utilizing the facilities at the Keys Marine Lab we collect brittle star specimens in ten to thirty feet of water around Long Key.We carry out a great deal of our wet laboratory work directly on premise at the Keys Marine Lab. While staying in the dormitories on site we can spawn animals, collect fertilized eggs and developing embryos at various stages of development where the larval skeleton begins to form. We can preserve animals, extract both DNA and RNA as well as perform microscopic injection of embryos while at the KML.
Work continues on the embryos and genetic material collected while at KML when we return to Tampa. Once back at USF we work to determine what genes are responsible for the larval skeleton that is characteristic of the brittle star. Our work will help to contribute to a better understanding of the networks of genes found within all cells that function as groups to accomplish individual functions or tasks. Without the facilities and staff of the Keys Marine Lab our work with this fragile and difficult-to-transported species would be nearly impossible.

KML Marina is Open!
The long-awaited marina at KML is operational! Our boat ramp is officially open for use. Be sure to check with our Operations Manager and Staff for access and use guidelines.
We are docking KML boats on site once again. Many thanks to our Layton neighbors for offering us courtesy dock space at Zane Grey Marina across the street while the marina project was under way.
In the coming weeks we will be adding additional mooring spots along the new seawall as well as power and wash-down stations.
Thank you to all of our KML guests for your patience during our re-building efforts.

Mangrove mitigation is completed
Site 1 at low tide
Site 1 at high tide
The second site at KML's Mangrove Point (the entrance to our marina) was mostly rubble and rock so we used terracotta strawberry pots lined with burlap to hold the soil around the mangrove seedlings. The 6 pots were partially buried among the rubble behind the new rip-rap. The pots should decay in a few years as the mangrove root system becomes established.
Site 2 at low tide
Site 2 at high tide
We will be monitoring our our new red mangrove seedlings at both sites in the coming months and anticipate adding more mangroves and other native plantings to the landscape.

University of Miami
Scientists working from the Keys Marine Lab are doing their part to investigate the effects of climate change, in particular, the phenomenon of ocean acidification. The
Based out of the Keys Marine Lab, the UM scientists are measuring coral calcification and photosynthesis in a wide array of environmental conditions. Additionally, the scientists are analyzing a 190-year old coral skeleton from the study site to reconstruct the water chemistry and determine how the coral has grown during the last two centuries. These experiments should indicate whether corals have indeed adapted or acclimated to changing CO2. If they have, then hope exists for corals in the future.
(photo: This core sample is from a star coral skeleton and represents ~50 years of growth. Scientists will attempt to reconstruct the history of Florida Bay from this skeleton.)

Sea wall & marina project is taking shape
The beautiful new sea wall at KML is really shaping up. This massive project began last fall with construction crews working long hours, often 6 days a week. The marina has been dredged and the big cranes and backhoes are gone now that the metal retaining wall is set, the pilings are in, and the boulders of rip-rap are in place.
Our new boat ramp is slowly materializing as concrete forms are pulled away. Quite a bit of work remains before the ramp and marina is usable.
The cement seawall cap is poured from the east end of KML, past the old observation deck and wet lab, and out to the old pump house. Progress has been slow but steady.
