Description

The effects of Hurricane Harvey were studied. This dataset includes biomass of benthic macrofauna from triplicate 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. Biomass is determined for higher taxonomic groupings by drying at 55 °C for 24 hours, and summed per sample.

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, R to richmess, nm2 to abundance, gm2 to biomass, lnm2 to log_abundance and lgm2 to log_biomass
- reduced precision of biomass, log_abundance and log_biomass from from 7-9 decimal places to 4

Instruments

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.
