Learning how to launch an expendable probe to measure temperature profiles from a moving ship aboard the RV Roger Revelle

Joint Program students and cruise watch leaders, Elena Perez (center right) and Lilli Enders (center left), begin their adaptive sampling through a Gulf Stream shingle by learning from RV Roger Revelle’s Brent De Vris (left) how an eXpendable BathyThermograph (XBT) can be used to provide a vertical profile of temperature without slowing the ship.  They developed the sampling plan with RR2407 co-chief scientist, Glen Gawarkiewicz, who is researching how shingles influence squid movements across the continental slope and whether a recent shingle contributed to a widespread scallop mortality event across the entire Mid Atlantic Bight shelf.

Snehal is also a member of Science Research on Commercial Ships (Science RoCS), a group that aims to increase scientists’ access to in situ observations by partnering with commercial vessels to collect underway measurements for science.
