Gawarkiewicz quiz help his colleagues accumulated additional data on water temperature quiz help salinity from December 4, 2011 via January 4, 2012, from contraptions on temporary test moorings placed 12 km south of the shelfbreak by the Ocean Observatories Initiative OOI. The researchers as compared those salinity measurements exam help historic data, quiz help found out that prime salinity levels according to the salinity of waters carried by the Gulf Stream coincided with the warming classes. The extent quiz help duration of the 2 2011 warming events combined with the high salinity accompanied by the researchers recommended the cause was not exam help transient warm core ring, but the Gulf Stream itself that carried warm, salty water examination help the outer shelf. To solidify that finding, Gawarkiewicz obtained serendipitous help from college students in the Marine Advanced Technology Education MATE software at Cape Fear Community College in Wilmington, NC, who had deployed exam help surface drifter throughout the period coinciding with the 2 warming events. Drifters use satellites examination help transmit their positions approximately every six hours, key information for the WHOI scientists, who analyzed the drifter tracks quiz help speeds. “Drifters around the edges of warm core rings drift toward the continental shelf at about 1 knot,” Gawarkiewicz says.
