Layer: Porosity (ID: 7)

Name: Porosity

Display Field: GA_Sample_ID

Type: Feature Layer

Geometry Type: esriGeometryPoint

Description: This data layer comprises porosity measurements on the upper 2 cm of seabed sediments. Bottom sediments were collected using either a Smith McIntyre grab or a Box Core. Bulk sub-samples (6.5 ml) of surface sediment (0-2 cm) were extruded into vials which were then frozen. Porosity was determined by calculation of the wet volume as a percentage of the total volume, after freeze drying and correction for seawater salts. The accuracy of the wet/dry measurements were greater than 1%. The precision of the volume measurements were greater than 2%.
