Into the Lab

There is always action on the deck of the R/V EDWIN LINK (RVEL). Scuba teams come and go. Twice a day, the 10-ton JOHNSON-SEA- LINK (JSL) submersible dives from the ship's stern into the deep waters that surround the island of Curaçao.
 
As scuba divers and submariners return with buckets and bags of collected organisms, the action moves to the interior of the EDWIN LINK. Every new collection of samples elicits a flurry of activity in the 'wet' lab. Researchers gather around the laboratory's large silver table like children gathering around the tree on Christmas morning.
Seen through a plastic bag holding a colorful sponge, researcher Brian Killday prepares for another
influx of samples.
It's fun to watch the scientists 'unwrap' their aquatic collections. As they dart back and forth, they seem torn -- eager to admire the strange and beautiful offerings of the sea, but knowing how important it is to keep their research process moving quickly.

In the RVEL's 'wet' lab, researchers sort, number and log samples from recent scuba and submersible operations.


The branches of this soft coral will soon be pulverized and tested to determine whether this species produces promising medical compounds.
It is critical to work while the specimens are fresh, and it is important to get everything right: all the logs, all the numbers...everything. As they sort, number, and photographically log the samples, the researchers wear surgical gloves to guard against contamination of the specimens.
 
Once all the samples are in order, the silver table becomes more like a dinner table for a large science family. Small pieces of promising organisms are hacked off and distributed among the scientific disciplines represented aboard the ship: microbiology, chemistry, cell biology, aquaculture. Each scientist contributes their particular disciplinary techniques toward answering the larger question: might there be a new cure in here? Samples and information flow freely between the groups, each offering thoughts and ideas to the others.
 
Previous research and (extremely) educated guesswork is suggesting that compounds generated by certain organisms collected today may have great medical potential. But, only time and lots of experimentation will tell for sure. In the coming days, these researchers will analyse the organisms' tissues, cells, and molecules with techniques that run the gamut of technical complexity. And every day, they will encounter the unique benefits and limitations of working at sea.
