Description

The effects of Hurricane Harvey were studied. This dataset includes abundance of identified benthic macrofauna from sediment core samples collected in San Antonio Bay, northwest Gulf of Mexico estuaries along the Texas coast. They were collected during eleven quarterly sampling trips on a small boat, Feb-July, 2019.

Methods & Sampling

Dataset acquisition description

Sediment samples were collected using cores deployed from small boats (Montagna and Kalke 1992). Macrofauna were sampled with a 6.7-cm diameter core tube (35.4 cm2 area). The cores were sectioned at 0-3 cm and 3-10 cm depths to ease the samples sorting and identification process for macrofauna but summed for whole core analyses here. Three replicates were taken per station. Organisms were extracted on a 0.5 mm sieve and enumerated to the lowest taxonomic level possible.

Data Processing Description

Dataset Processing Description

BCO-DMO Processing Notes:
- added conventional header with dataset name, PI name, version date
- renamed columns: DATE to date_local, REP to replicate, SP to species_code, n to count, and nm2 to abundance
- reordered columns

Instruments

Microscope - Optical

Supplied Name: Wild steromicroscope

Supplied Description:

Used to identify macrofauna.

Instrument Type

Generic Name: Microscope - Optical

Community Identifier: http://vocab.nerc.ac.uk/collection/L05/current/LAB05/

Generic Description:

Instruments that generate enlarged images of samples using the phenomena of reflection and absorption of visible light. Includes conventional and inverted instruments. Also called a "light microscope".

Push Corer

Supplied Name:

Supplied Description:

Used to collect sediment core samples.

Instrument Type

Generic Name: Push Corer

Generic Description:

Capable of being performed in numerous environments, push coring is just as it sounds. Push coring is simply pushing the core barrel (often an aluminum or polycarbonate tube) into the sediment by hand. A push core is useful in that it causes very little disturbance to the more delicate upper layers of a sub-aqueous sediment.
