The structure allows for the sampling of near surface phenomena as the Profiler travels up through the water and breaches the surface. Fine resolution sampling of the water column, particularly at the very surface of the water, provides key insights into the production of phytoplankton and the exchange of gases between the atmosphere and the ocean. While on the surface, the profiler transmits data to shore.<\/p>\n<p><img loading=\"lazy\" class=\"alignnone wp-image-533425\" src=\"https:\/\/www2.whoi.edu\/site\/ooi-expedition\/wp-content\/uploads\/sites\/143\/2022\/09\/Mooring-3.png\" alt=\"\" width=\"600\" height=\"494\" srcset=\"https:\/\/www2.whoi.edu\/site\/ooi-expedition\/wp-content\/uploads\/sites\/143\/2022\/09\/Mooring-3.png 722w, https:\/\/www2.whoi.edu\/site\/ooi-expedition\/wp-content\/uploads\/sites\/143\/2022\/09\/Mooring-3-300x247.png 300w\" sizes=\"(max-width: 600px) 100vw, 600px\" \/><\/p>\n<p>After a brief break, the Team set about multi-tasking on the rear deck.\u00a0 They spent a large part of the afternoon assembling the pieces for tomorrow\u2019s big launch of the Washington Offshore Surface Mooring, another 8,000-pound behemoth.<\/p>\n<p><img loading=\"lazy\" class=\"alignnone wp-image-533426\" src=\"https:\/\/www2.whoi.edu\/site\/ooi-expedition\/wp-content\/uploads\/sites\/143\/2022\/09\/Mooring-4.png\" alt=\"\" width=\"600\" height=\"799\" srcset=\"https:\/\/www2.whoi.edu\/site\/ooi-expedition\/wp-content\/uploads\/sites\/143\/2022\/09\/Mooring-4.png 552w, https:\/\/www2.whoi.edu\/site\/ooi-expedition\/wp-content\/uploads\/sites\/143\/2022\/09\/Mooring-4-225x300.png 225w\" sizes=\"(max-width: 600px) 100vw, 600px\" \/><\/p>\n<p>Somehow, they found the time, interspersed between assembly tasks, to launch two gliders .\u00a0 The gliders will stay in the water for the next three months, providing invaluable information about conditions in the water column from the coast to the edge of the continental shelf in this extremely productive and economically important area.<\/p>\n<p>After re-arranging the deck to make tomorrow\u2019s launch easier, the ship\u2019s crew launched a CTD (conductivity, temperature, and depth) Rosette.\u00a0 Conductivity is a proxy for salinity.
