Description

Discrete hydrographic measurements of Lavaca-Colorado, Guadalupe and Nueces Estuaries on the Texas coast between August 2017 and January 2018 to test the effects of Hurricane Harvey on estuarine water quality.

Methods & Sampling

Multiple hydrographic measurements were made at the stations Lavaca-Colorado (LC), Guadalupe (GE) and Nueces Estuaries (NE) on the Texas coast, using a YSI Proplus multi-parameter instrument (The parameters were read from the digital display unit). Vertical profiles of Sal, Cond, DO, DOPct, pH and Temp were taken at 0.5 m intervals. Discrete samples were collected at 10 cm below the surface and for some variables at 10 cm above the bottom. Secchi disc was lowered until it could no longer be viewed.

Sampling trips/deployments were conducted from one of five small (≤25’) outboard engine equipped boats: Guardian, Mango, Stinger, Gator, or Guppy. Each cruise was less than 12 hrs in duration.

Additional methodological details can be found in Wetz et al. 2016.

Data Processing Description
