These data were obtained from the LANL plasma experiment on ICE (Principal Investigator: S.J. Bame assistance from K. Sofaly and S. Kedge). The instrument measures the 2-D electron distribution function in one spacecraft rotation (3 s) once every 24 s, by obtaining 16 evenly spaced energy spectra, each with 15 contiguous levels covering the energy range 8.5 eV to 1140 eV. From these 2-D distributions the density, velocity, and temperature of the electrons are then derived. A 2-D temperature matrix is calculated which is subsequently diagonalized. Then nominally the maximum temperature corresponds to the parallel temperature and the minimum temperature corresponds to the perpendicular temperature. This is done independently of the magnetic field measurements however, the direction of maximum temperature determined in this manner is usually found to be within 15 degrees of the magnetic field direction inferred from the magnetometer measurements. The time resolution is 24 sec from the start of Day 253 (September 10) until Day 255 (September 12), 18:38. At that time the bit rate dropped from 1024 to 512 bps, and the nominal time resolution went to 48 sec.

The data are presented as the values of the density and temperature of the electrons measured (radio mapping) during the tail crossing of comet Giacobini-Zinner by ISEE-3/ICE as derived from spectroscopy of the thermal noise spectrum. The data was provided to the National Space Science Data Center (NASA/GSFC) by the Principal Investigator of the Radio Mapping Experiment on ISEE-3/ICE, Dr. Jean-Louis Steinberg of the Observatoire de Paris, Meudon, France cover the time interval 10:00 - 12:00 UT on September 11, 1985. The time resolution is 54 seconds.

These data were used to create Fig. 1 of “Monte Carlo Evaluation of the Europa Clipper TID Margin based on the Variability of the Jovian Radiation Environment with Application for Mission Design” by Allen Andersen, Wousik Kim, Steven McClure, and Insoo Jun of the Jet Propulsion Laboratory, California Institute of Technology. This data set contains Galileo Energetic Particle Detector (EPD) average counts per second measurements of 3.2-10.1 MeV protons (B0), 1.5-10.5 MeV electrons (B1), and >11 MeV electrons (DC3) between 8-10 Jovian Radii (Rj) only. Each entry has a corresponding time stamp and orbit name. Further details regarding these data can be found in Jun, I., Garrett, H. B., Swimm, R., Evans, R. W., and Clough, G.

This record describes the data (CTD, Dissolved Oxygen, Transmissometer, PAR, ECO Triplet, Nitrate, Fluorescence and LOPC) collected using the towed TRIAXUS platform on Investigator voyage IN2023_V07, titled: "SWOT-ACC: smaller scales of the Antarctic Circumpolar Current in a meander south of Tasmania." The voyage took place between November 15, 2023 and December 20, 2023 (AEST), departing from Hobart and returning to Hobart. The primary focus of this voyage was to enhance our ability to observe and comprehend the effects of small-scale motions (ranging from 10 to 100 km) on the dynamics of the Antarctic Circumpolar Current (ACC). The groundbreaking Surface Water Ocean Topography (SWOT) satellite mission will provide unprecedented measurements of sea surface height over a wide area with substantially improved spatial resolution compared to traditional altimeters. While SWOT will offer unparalleled coverage in both space and time, it is crucial to obtain in situ subsurface ocean measurements to validate the satellite observations and establish the connection between small-scale variability in sea surface height and subsurface ocean circulation and dynamics. The objective was to gather comprehensive multidisciplinary measurements along a swath traversing a standing meander of the ACC. This meander represents a region of intense eddy activity, cross-front exchange, and vibrant small-scale motions. The experiment's goals encompass characterizing the small-scale variability within this meander, establishing a correlation between small-scale variations in sea surface height and subsurface ocean structure, quantifying the contribution of small-scale processes in facilitating the transport of heat and carbon across the ACC, and investigating the interconnectedness of physical, biogeochemical, and biological processes at small spatial and temporal scales. 5 Triaxus tows were conducted. Pressure, conductivity, temperature, and dissolved oxygen data were gathered from duplicate sensors using a Seabird SBE9plus CTD. Also carried on the Triaxus hull were a cosine Photosynthetically Active Radiation (PAR) sensor, a transmissometer, an ECO Triplet (optical backscatter, CDOM fluorometer and chlorophyll fluorometer), a Laser Optical Plankton Counter (LOPC) and SUNA nitrate sensor. Triaxus hull number 2 was utilized throughout the entire voyage, completing 5 tows with a total towing time of 121.75 hours. The vehicle was generally towed between 5-7 knots depending on the conditions. Overall, it performed well during the entire voyage. The following issues were encountered: • There were 5 instances (Tow1) when the Triaxus software crashing and Seasave stopping. Fortunately, after multiple restarts, it returned to normal operation once payloads and undulations were reset. Additionally, on two occasions, the software failed to maintain the designated undulation schedule and required a restart to execute undulations correctly. • During tow #3, halfway through, the secondary DO sensor #3534 was replaced with #1794. The DOs were in specification however this brought the reading closer together. During the beginning of Tow 3, the Suna data for Triaxus was not displaying on Grafana, leg-2 was thus aborted. • On several of the tows, the fairing became loose from the cable and thrashed in the current. Eventually, the method outlined in IN2023_V06 for securing the fairing was adopted. This involved using regular-sized cable ties and hose clamps spaced approximately 300mm apart along the fairing to keep it securely attached to the sea cable. • During Triaxus tow 4 on December 5th a malware attack was encountered, corrupting the network share drive containing CTD data. The tow was promptly aborted at 0830 UTC, and the vehicle was safely recovered without incident. For more detailed information on the malware attack, please refer to the DAP report. On each tow only data from legs where the Triaxus was vertically undulating regularly were processed. Data from
