\"LCA fleet of 20-25 autonomous profilers deployed in the Loop Current System (LCS) active area in the eastern Gulf of Mexico are part of the NAS Understanding Gulf Ocean Systems campaign, and provide publicly-available near-real-time data to weather forecast models to aid in hurricane prediction.\u00a0 These data are also being used in conjunction with c-PIES data to explore the physical mechanism of Loop Current expansion into the Gulf and subsequent Loop Current Ring formation.\u00a0 Read More<\/span>

These Argo-equivalent floats drift at 1500 m and measure temperature and salinity from the sea surface to 2000 m every five days, generating 120-150 profiles and deep velocity measurements every month. These instruments are considered standard Argo floats, and all data is being made publicly available in near-real time (within 24 hours) and in final form (within 6-12 months) via the Global Telecommunications System (GTS) and global Data Assembly Center (GDAC). The project team includes U.S. and Mexican scientists with deep end-to-end experience in the use of floats for oceanographic studies in the Gulf of Mexico and worldwide, from procurement, ballasting and communications, to calibration, data processing and data delivery, to scientific analysis and publication of results. The profile and velocity data collected by this fleet of profilers will be valuable to scientists and forecasters in numerous ways, such as stated above: for data assimilation and Loop Current prediction, weather and hurricane forecasting, as well as deep oil spill tracking. Additionally, the team will generate statistical data products for comparison with past LCS studies and to assist with planning the long-term LCS campaign. <\/div>\n\t
