Turtles, turtles, and more turtles!

With a successful sea turtle nesting season closing at the end of October, things in the Turtle-World of Long Key are anything but slow!

Since the middle of November there have been 2 dead juvenile Green sea turtles (Chelonia mydas) that have floated up into and around the KML marina. Another Green with fibropapilloma (fp) practically swam right up our boat ramp and was rescued along with a sub-adult Loggerhead sea turtle (Caretta caretta) that had monofilament fishing line coming out of its mouth and wrapped around the left front flipper.

Both turtles were picked up by staff from The Turtle Hospital in Marathon and are receiving care for their aliments.

Winter plowing duties at KML

Well it's winter again in the Florida Keys, heralded by those cold fronts and north winds. Dealing with all of the rack accumulation in the marina, at the boat ramp, and the lagoon around our seawater intake is a constant headache.
But Dave and Bill were not to be thwarted! Engineering a Keys version of a marine plow and harnessing the muscle of our little 13' Boston Whaler, they guys pushed loads of rack and weed back out into the Bay. Frustrated snowplow operators?!?

We are happy to report that in spite of the frequent rack accumulation in the Lagoon by the Wet Lab this time of year, the water quality continues to be excellent for our seawater system.

USF Fish Biology Class

Dr. David Mann, from the University of South Florida, brought his Marine Fish Biology class to KML. They spent the week gaining experience identifying fish in various habitats of the Florida Keys.

R/V Mola Mola leaving KML marina

Several of the Mann students were AAUS dive certified. They prepared their dive gear aboard the R/V Diodon and listened to KML dive safety protocols with Captain Andrew Crowder before a day of diving. To the Reef!

The group snorkeled over a grass flat to explore fish communities among the roots of a mangrove island. Water temperature 70F! Brrr!

The USF students snorkeled Coral Gardens at dusk to observe the change in fish activity on the reef. Weather was perfect all week and the sunset was spectacular.

Spotted Eagle Rays visit KML

Two juvenile spotted eagle rays (Aetobatus narinari) spent the afternoon cruising around the KML Lagoon last week. The little guys seemed intent on corralling a small school of mullet and took turns darting through the middle of them. One poor mullet had a hole in his side to document the strike!

Clemson students field-test KML Living Laboratory Project

Clemson University and the KML Living Laboratory.

The Clemson University Conservation of Marine Resources creative inquiry team participated in the first biodiversity census of the KML Living Laboratory.

Learning the Biodiversity of the Keys.

The CMR team, under the direction of Dr. Michael Childress, helped set-up and census four biodiversity plots including one in the hardbottom habitat adjacent to the Keys Marine Laboratory.

Learning to Measure Biodiversity.

Graduate student teaching assistant TJ Jordan leads the students through a dry-run of the data collection methods that use line, belt and whole plot census methods to enumerate the density of benthic invertebrates and fishes.

Laying Out a Census Plot

Dr. Michael Childress directed CMR students in the all-important placement of grid lines prior to data collection. He then snorkeled amongst them to answer questions and assist in correctly identifying organisms.

Taking Data While on Snorkel

The CMR students collected data on the type of benthic substrate and the density of sponges, corals, octocorals, anemones, echinoderms, mollusks, crustacaeans, and benthic fishes.

Assessing the Impact of Mass Sponge Mortality

In the fall of 2007, a mass sponge mortality occurred on Florida Bay side of Long Key killing a majority of large sponges such as this ancient loggerhead sponge. The KML Living laboratory project will monitor and document the changes in biodiversity on both impacted and non-impacted sites to assess the impact of this most recent disturbance.

KML Living Laboratory Seeks Volunteers

Classes visiting KML are invited to participate in the KML Living Laboratory project. For more information regarding how to get involved please contact KML staff biologist Cindy Lewis
