Description: Processed results from of analysis of the sediment grab samples recovered as part of the Long Island Sound mapping project Phase II.
Sediment grab samples have been taken in summer of 2017 and 2018 using a modified van Veen grab sampler. A sub-sample of the top two centimeter was taken and stored in a jar. Sub-samples were analyzed between March 2018 and July 2022 to determine matrix density (g/cm3).
Attributes:
Sample_ID = grab sample identifier
SAMPLE_NAME = survey ID + grab sample ID
lat = latitude position
lon = longitude position
Date_Analyzed = date of analysis
matrix_den = matrix density (g/cm3)
SD = standard deviation
RSD = relative standard deviation
SamplDesc = survey sample description
Filename = sample analysis file
Operator = sample analyzer
