Both deck operations went smoothly. The mooring was deployed by lowering each of its parts off the deck into the ocean using the winch, beginning with its anchor, acoustic releases, and bottom pressure recorder, followed by its profilers (which measure temperature, salinity, and velocity), other sensors (e.g., CO<sub>2<\/sub>, oxygen, and pH), and lastly, its large yellow sphere which holds the line of instruments upright, and contains an upward looking sonar which provides estimates of sea ice thickness. The mooring deployment took about 5 hours. ITP 143 was deployed in a similar manner, with its weights and profiler (which provides temperature, salinity, pressure, and oxygen measurements) lowered over first, followed by its near-surface sensors (which measure CO<sub>2<\/sub>, oxygen, pH), and finally its yellow surface float, which also has a unit to transmit data back to land via satellite. It was a productive day on the forward deck to say the least!<\/p>\n<p>Once mooring and buoy operations were complete, the Louis began steaming south down the 150\u00b0W longitude line towards station CB-8, where we completed CTD\/bongo casts. We are now continuing to steam south towards our next set of stations, while keeping a close eye on the location of an old Tethered Ocean-Profiler (TOP) in hopes we get the chance to recover it.<\/p>\n\t\t\t\t<img loading=\"lazy\" src=\"https:\/\/www2.whoi.edu\/site\/beaufortgyre\/wp-content\/uploads\/sites\/108\/2024\/09\/map-12.png\" alt=\"Map of our current location.\" height=\"442\" width=\"580\" title=\"map\" \/>\n\t\tMap of our current location.\n\t\t\t\t<img loading=\"lazy\" src=\"https:\/\/www2.whoi.edu\/site\/beaufortgyre\/wp-content\/uploads\/sites\/108\/2024\/09\/Photo1-8.jpg\" alt=\"The moored profiler (which will measure velocity, temperature, salinity, and pressure on the mooring) is deployed (Photo by Mary-Louise Timmermans)\" height=\"794\" width=\"598\" title=\"Photo1\" \/>\n\t\tThe moored profiler (which will measure velocity, temperature, salinity, and pressure on the mooring) is deployed (Photo by Mary-Louise Timmermans)\n\t\t\t\t<img loading=\"lazy\" src=\"https:\/\/www2.whoi.edu\/site\/beaufortgyre\/wp-content\/uploads\/sites\/108\/2024\/09\/Photo2-10.jpg\" alt=\"The top flotation sphere of mooring B is lifted out of the ship's forward hold (Photo by Mary-Louise Timmermans)\" height=\"763\" width=\"1011\" title=\"Photo2\" \/>\n\t\tThe top flotation sphere of mooring B is lifted out of the ship&#8217;s forward hold (Photo by Mary-Louise Timmermans)\n\t\t\t\t<img loading=\"lazy\" src=\"https:\/\/www2.whoi.edu\/site\/beaufortgyre\/wp-content\/uploads\/sites\/108\/2024\/09\/Photo3-9.jpg\" alt=\"The final components of the mooring are ready for deployment (Photo by Mary-Louise Timmermans)\" height=\"892\" width=\"672\" title=\"Photo3\" \/>\n\t\tThe final components of the mooring are ready for deployment (Photo by Mary-Louise Timmermans)\n\t\t\t\t<img loading=\"lazy\" src=\"https:\/\/www2.whoi.edu\/site\/beaufortgyre\/wp-content\/uploads\/sites\/108\/2024\/09\/Photo4-9.jpg\" alt=\"A view from the bridge as mooring B is released from the ship (Photo by Mary-Louise Timmermans)\" height=\"629\" width=\"831\" title=\"Photo4\" \/>\n\t\tA view from the bridge as mooring B is released from the ship (Photo by Mary-Louise Timmermans)\n\t\t\t\t<img loading=\"lazy\" src=\"https:\/\/www2.whoi.edu\/site\/beaufortgyre\/wp-content\/uploads\/sites\/108\/2024\/09\/Photo5-3.jpg\" alt=\"ITP 143 surface package and SAMI suspended over the deck for deployment\" height=\"843\" width=\"635\" title=\"Photo5\" \/>\n\t\tITP 143 surface package and SAMI suspended over the deck for deployment\n\t\t\t\t<img loading=\"lazy\" src=\"https:\/\/www2.whoi.edu\/site\/beaufortgyre\/wp-content\/uploads\/sites\/108\/2024\/09\/Photo6-1.jpg\" alt=\"Jeff O'Brien and Tim McDonough performing a systems check on the ITP before it is released\" height=\"690\" width=\"916\" title=\"Photo6\" \/>\n\t\tJeff O&#8217;Brien and Tim McDonough performing a systems check on the ITP before it is released\n\t\t\t\t<img loading=\"lazy\" src=\"https:\/\/www2.whoi.edu\/site\/beaufortgyre\/wp-content\/uploads\/sites\/108\/2024\/09\/Photo7.jpg\" alt=\"ITP 143 set free to collect data\" height=\"825\" width=\"620\" title=\"Photo7\" \/>\n\t\tITP 143 set free to collect data\n\n","protected":false},"excerpt":{"rendered":"<p>Dispatch 14: Mooring B and ITP 143 are deployed!
