Abstract:

This dataset contains photographs of sediment cores collected aboard R/V Weatherbird II cruises WB-0717 (2017-07-19 to 2017-07-28) and WB-1217 (2017-12-05) in the northern Gulf of Mexico from 2017-07-19 to 2017-12-05. Sediment cores were longitudinally split and photographed with a digital camera with a scale in metric units (cm and mm) for a visual representation of sediment stratigraphy, color, and visual properties. The dataset includes the location, date and depth at which sediment cores were collected.

Purpose:

Visually describe and assess sediment cores for stratigraphy and stratigraphic integrity as well as identify visual indications in changes in sedimentation.

Data Parameters and Units:

The dataset contains sediment core photographs (unitless). An excel spreadsheet contains the site ID, core ID, water depth (meters), latitude and longitude (decimal degrees), and core collection date (MM/DD/YYYY) for each sediment core photographs. Sediment core photographs (Jpeg image files) are named as - . The dataset also includes the cruise documentation for the R/V Weatherbird II cruises WB-0717 and WB-1217, led by chief scientists Dr. Steve Murawski, Dr. David Hollander, and Dr. Patrick Schwing.

Methods:

Cores were split longitudinally into 2 halves.

Instruments:

Ocean Instrument MC-800 Multicore, Shipek Grab Sampler, Nikon D5200.
