Title: California Underwater Glider Network - Along Shore Transect

Summary:
The overarching goal of the California Underwater Glider Network is to sustain baseline observations of climate variability off the coast of California. The technical approach is to deploy autonomous underwater gliders in a network to provide real-time data.
The CUGN uses Spray underwater gliders making repeated dives from the surface to 500 m and back, repeating the cycle every 3 hours, and traveling 3 km in the horizontal during that time. The CUGN includes gliders on three of the traditional cross-shore California Cooperative Oceanic Fisheries Investigations (CalCOFI) lines: line 66.7 off Monterey Bay, line 80 off Point Conception, and line 90 off Dana Point.
 The glider missions typically last about 100 days, and cover over 2000 km, thus providing 4-6 sections on lines extending 300-500 km offshore. Since 2005 the CUGN has covered 200,000 km over ground in 28 glider-years, while doing 90,000 dives.

Title: Gliders in the Gulf Stream

Summary:
The overarching goal of this project is to collect high resolution transects across the Gulf Stream. Though the speed of the Gulf Stream greatly exceeds the speed of a glider, gliders can be flown across the current as they are advected downstream. Missions prior to 2015 were conducted downstream (northeast) of Cape Hatteras, primarily between Cape Cod and Bermuda; missions since 2015 begin in Miami, FL and are planned to end on the New England continental shelf. During a typical 100-day mission between Miami and Cape Cod, a single glider completes 6-10 crossings of the Gulf Stream, returning approximately 800 profiles to the shallower of the sea floor or 1000 m. The current operational goal is to maintain at least one glider in the Gulf Stream at all times. Additional plots of these data are available at http://gliders.whoi.edu.

Title: Science Quality, Delayed Mode, Full Resolution Spray Data Collection

Summary:
Full-resolution, delayed mode, science quality Spray glider data. This data collection supercedes corresponding near-real-time data distributed through the National Glider DAC and other channels. This delayed mode data product should be used over the near-real-time version once it is available. Spray glider missions are post-processed after a mission is complete.  This full-resolution, delayed mode product represents the highest quality most complete data record for Spray missions. Data from these missions are available in two other data products: the near-real-time data product and the binned project level data product. The near-real-time data streams are not as complete or accurate as this product due to data telemetry limitations and the nature of near-real-time data dissemination. The binned project level data product is derived from the delayed-mode quality-controlled full-resolution data. The binned product offers the data in an easier to work with format and provides the data at 10 meter vertical resolution, while this full-resolution data product is available for advanced data users who require higher resolution observations.

Title: Seasonal-to-Interannual Modulation of Fine-Scale Thermohaline Structure

Summary:
The overarching goal of this project was sustained sampling of upper ocean hydrography to resolve the seasonal-to-interannual modulation of meso- and fine-scale thermohaline structure. To achieve this goal, Spray underwater gliders made repeated occupations of a 1300-km meridional section northward from Hawaii to 34.5N along 158W.  The data set includes 1014 glider-days, covering 22566 km over ground, 22720 km through water, with 4641 dives.

Title: Solomon Sea Ocean Transport from Gliders

Summary:
The western boundary current of the South Pacific Tropical Gyre flows through the Solomon Sea and then to the equator. The degree to which this flow affects the equatorial zone and global climate depends on its transport of water and heat. These transports have been measured since 2007 by underwater gliders crossing the Sea seasonally to monthly. Ocean temperature and salinity profiles and depth-average current are measured every few km to depths of 500 to 1000 m. Velocity shear can be inferred from measured density. Phenomena of interest are El Nino - Southern Oscillation (ENSO) and flow in the Equatorial Undercurrent.

Title: Southern California Water Temperature Index, 10-day, v1.0

Summary:
The Southern California Temperature Index (SCTI) is derived from the sea water temperature records of the California Underwater Glider Network (CUGN), a collection of over 15 years of Spray underwater glider measurements. The CUGN data provides climatologies and the interannual anomaly of the sea water temperature near the California Coast which are used to generate the SCTI.
        The Southern California Temperature Index represents a smoothed temperature anomaly variability near the coast of California, similar to the Oceanic Nino Index (ONI), using local in-situ data to provide a regional index. The Socal Index is calculated using a subset of the CUGN Line 90 glider climatology data. The index is created using water temperature data at 50-m depth for the nearhsore 200-km section of all Line 90 data extending back to 2006. These data are averaged over the 200-km section to provide a time-series of the average temperature for this area at 50-m depth. The glider data is then averaged at a 3-month (90-day) interval. This aligns the time signature of the index with the ONI and allows for comparison of the two data products. The SCTI data are updated monthly after the monthly NOAA Nino 3.4 data are released.
        An Oceanic Niño Index variable is included with the SCTI. This variable is calculated using the Niño 3.4 index, and applying a 3-month average to it. The Niño 3.4 index is obtained from the NOAA Climate Prediction Center.

Title: Spray glider data in support of mooring observations from the CORC project in the California Current starting 2007

Summary:
CORC (Consortium on the Ocean\'s Role in Climate) has been making observations of the California Current systems with moorings since 2008. In support of these mooring deployments, gliders have been used that serve as data shuttles to communicate with the underwater mooring gear, as well as collect additional data near or between the moorings. These glider operations are done by PI U. Send, and are in addition to repeat glider sections by PI D. Rudnick in the same general area. Glider data reported here are temperature and salinity, as well as column-average currents based on lateral glider displacement between dives.

Title: Spray glider observations in support of MAB-SWOT

Summary:
During the first several months of the Surface Water and Ocean Topography (SWOT) satellite mission, the satellite was in an orbit that passed over select locations twice per day (one ascending and one descending pass). One of these 'cross-overs' was located offshore of Cape Hatteras, NC where the Gulf Stream detaches from the continetal margin. In support of the calibration and validation of the SWOT measurements of sea surface topography, Spray gliders sampled within this cross-over as part of the SWOT Adopt-A-Crossover - MAB-SWOT campaign (https://www.swot-adac.org/campaigns/mab-swot/) in 2023. Gliders primarily attempted to hold station at the center of a triangular array of CPIEs just north of the Gulf Stream. Additional plots of these data are available at https://gliders.whoi.edu.

Title: Spray glider observations in support of NASCar

Summary:
Spray gliders surveyed from the northern edge of the Mascarene Plateau, crossing the equator repeatedly, then surveyed southward back toward the Seychelles prior to recovery. One glider mission was conducted in each of 2017 and 2018. Missions were timed to capture the onset of the southwest (northern hemisphere summer) monsoon at the equator.  Additional plots of these data are available at http://gliders.whoi.edu.

Title: Spray glider observations in support of PEACH

Summary:
The overarching goal of PEACH is to understand the dynamics controlling exchange of waters between the continental shelf and deep ocean in the region near Cape Hatteras, North Carolina. As part of PEACH, Spray gliders surveyed along the upper continental slope and across the outer continental shelf for more than two years during a series of missions from spring 2017 to spring 2019. Typical sampling was to a maximum depth of 500 m or to within a few meters of the seafloor in shallower water; occasional deeper sampling occurred if gliders encountered adverse currents. Additional plots of these data are available at http://gliders.whoi.edu.
