Spatial Information

All samples contained within (37º39’N, 76º54’W), (37º16’N, 76º20’W), (37º8’N, 76º24’W), (37º34’N, 76º0’W)

Abstract

Dataset consists of all sampling cruises with data that were analyzed and used in the statistical modeling associated with Wright (2021) and Wright et al. (2022). Each cruise folder includes erodibility data that was analyzed using a Gust Microcosm along with sediment and water column characteristics.

Description

During each sediment survey, the vessel was anchored and all sediment samples were taken within the swing circle of the vessel and its anchor chain. Samples were taken using a GOMEX Box Core (surface area = 625 cm2), then sub-cores were collected to minimize edge effects that would disturb the sediment/water interface. At each site, the top ten centimeters, if possible, from two 4” diameter sub-cores were sliced in 1 cm increments and combined for later analysis in the lab for grain size (sand, silt, and clay) distribution as well as percent moisture and percent volatile content by loss on ignition at 550 degree Cº. Two additional 4” diameter cores were analyzed for sediment erodibility using a Gust Microcosm, and two rectangular cores were imaged by digital X-ray analysis. Salinity and temperature profiles were collected at each site with a CTD. For more complete methodology, see Wright (2021) and Wright et al. (202x) (See Associated Publications below).

Each folder represents a single sampling cruise. Each folder name begins with “YR” (representing “York River”) followed by six numbers which represent the date of sampling in the format YYMMDD. For example, August 31, 2014 would be YR140831.
