title: Location and Processed results (XLS format) from surface grain size analysis of sediment grab samples, Long Island Sound mapping project Phase II

description: Sediment grab samples were taken in summer of 2017 and 2018 using a modified van Veen grab sampler. A sub-sample of the top two centimeters was stored in a jar. Dried sub-samples samples were analyzed for grain size. First, the samples were treated with hydroperoxide to remove organic components. Then, the sample was passed through a series of standard sieves representing Phi sizes with the smallest being 64 µm. The content of each sieve was dried and weighed. If there was sufficient fine material (&lt; 64 µm), this fine fraction was further analyzed using a Sedigraph system. The results of sieving and sedigraph analysis have been combined and the percentages for gravel, sand, silt and clay were determined following the Wentworth scale. In addition, other statistics including mean, median, skewness and standard deviation are calculated using the USGS GSSTAT program. The results of the LDEO/Queens College grain size analysis have been combined with data collected by the LISMARC group and analyzed by USGS. Based on the different percentages, sediment classifications are determined following the Schlee and the Falk systems. These results are also translated into the CMACS systems. The data is presented here as an Excel spreadsheet. There is an accompanying ESRI shapefile. Funding was provided by the Long Island Sound Mapping Fund administered cooperatively by the EPA Long Island Sound Study and the Connecticut Department of Energy and Environmental Protection (DEEP).

title: Near-bottom magnetic anomaly and magnetization data (netCDF grids) from 9°50'N, East Pacific Rise, acquired in 2018, 2019 and 2021 during AUV Sentry dives

description: Near-bottom magnetic data was collected during a total of 20 AUV Sentry dives conducted from R/V Atlantis and R/V Roger Revelle during 2018 Atlantis cruise AT42-06 (three dives); 2019 Atlantis cruise AT42-21 (ten dives); and, 2021 Revelle cruise RR2102 (seven dives). Track lines were spaced 170 m apart, with Sentry about 70 m above bottom, collecting magnetic data using three Applied Physics Systems Model 1520 triaxial fluxgate magnetometers mounted on AUV Sentry. Sentry navigation was obtained using a 300 kHz Teledyne Doppler velocity log (DVL) and a Sonardyne AvTrak2 ultra-short baseline (USBL) acoustic positioning system, combined with an iXblue Phins inertial navigation system (INS), and a Paroscientific 8B7000-I Digiquartz depth sensor. The magnetic data was gridded at 10 m × 10 m node resolution. The grid files are in GMT-compatible netCDF format, in un-projected geographic coordinates. Three grid files are presented here, as follows. File 2400mergeT.grd is the total magnetic field anomaly, upward continued to 2400 m below sea-level. File const20anni.grd is the total field crustal magnetization, calculated using constant layer 2A thickness of 500 m. File var20anni.grd is the total field crustal magnetization, calculated using variable layer 2A thickness, constrained from seismic reflection images (Harding et al., 1993; Marjanovic et al., 2018).
