MSI Session 2

On Monday morning seven new Marine Science Interns arrived!

Over the past three days, the interns have acquired a comprehensive knowledge of over 50 species of fish native to Bermuda waters. By conducting three different types of fish surveys, the interns have learned to apply their new knowledge to the field. 

On Tuesday, the interns conducted belt transect and roving diver fish counts at both Bailey’s Bay Flatts and Crescent Reef.

On Wednesday, they learned how to do stationary point counts along a 30 meter transect. They used this skill to observe fish density at Rock-up Reef and Hog Breaker.

In their own words:

“It rained the first day, but we still leaned valuable skills like how to determine what makes up the ocean floor by randomly placing dots on pictures then recording what was under each dot in each photo. We also started to familiarize ourselves with common Bermudian fish to prepare ourselves for the next day.
On Tuesday, we went out on R/V Rumline to two dive sites and it was a great experience because we did the transect line surveys which is what real scientist do, so that was cool.”

Also, former intern, Eliza Gardner, has been helping out with this MSI session!

24 Hours Cruise on the R/V Atlantic Explorer

Last Thursday I, Kätchen Lachmayr, education intern here at BIOS, was presented with the unique opportunity to venture aboard the Atlantic Explorer and join them on a short two-day cruise to Hydrostation S and BATS.

Saying goodbye to BIOS

The AE departed from BIOS at approximately 11am on Thursday, after a safety meeting where we were instructed on where life jackets were, how to deploy a life raft, and practicing how to put on a survival suit.  The there were a total of 22 people on this voyage, five of them were other BIOS interns: Michel Chang, Ashley Berry, Will Halliday, and David Picton. 

The first stop was Hydrostation, which took about 2 hours to get to from BIOS. Once the AE arrived at Hydrostation, a CTD (left) was lowered into the water, and down to 4,000 meters! On the outside of this contraption were about 40 jugs that open at different depths to collect the seawater. Inside one of the labs on-board there is a computer that displays the depth that the device is at, the temperature and salinity of the water. It took a total of three hours to collect all the samples. The water samples are then used in number of the different labs back at BIOS, including CDOM and biogeochemistry.

The next stop was BATS, 50 miles off the coast of Bermuda! When the AE arrived at BATS a similar operation was conducted and the CTD was again lowered into the water to collect samples, this time only to 1,500 meters.  By the time all the samples at BATS had been collected it was midnight. A few other samples were collected for various labs, however I was not awake to see them. In the morning, we began our voyage back to BIOS a six-hour cruise from BATS.

Thankfully we had calm sea during the whole trip. This was quite the experience!
