Hurricane Harvey impacts on biogeochemistry of water assessed using samples collected in Mission-Aransas Estuary in south Texas from June 2017 to March 2019

Abstract:

The impact of Hurricane Harvey on the chemical composition of water was assessed using samples collected from June 2017 to March 2019 at Mission-Aransas Estuary in south Texas. Hydrographic measurements including temperature, salinity, dissolved oxygen, and pH were collected on site using a YSI sonde. Water samples were obtained from both surface and bottom depths at 19 sites, and later analyzed for dissolved nutrients, organic carbon and nitrogen, and pigments.

Methods & Sampling

Water samples were collected from both surface and bottom depths at 19 sites in the Mission Aransas Estuary. Hydrographic measurements including temperature, salinity, dissolved oxygen, and pH were collected on site using a YSI sonde. Upon return to the lab on the same day, 200 to 1000 milliliters of the collected water was filtered through pre-combusted 47 mm glass fiber filters (Whatman GF/F, 0.7 µm), which were frozen immediately at -20 ºC until analysis.

Organic carbon and nitrogen
The GF/F filters were first acidified to remove inorganic carbon by acid fumigation according to Hedges and Stern (1984). The organic carbon and nitrogen content in these samples was then measured using a Thermo FLASH 2000 CHN Elemental Analyzer. Precision for the C/N content is within 5%.

Pigment analysis
The glass fiber filter was transferred into a 15 mL polypropylene centrifuge tube, to which 3 mL acetone was added for pigment extraction (Sun et al., 1991). The mixture was sonicated for 15 minutes, and then centrifuged for another 10 minutes. The acetone extract was filtered with a syringe filter (0.2 µm Nylon filter) and the procedure was repeated on the GF/F using fresh acetone. The two extracts were then combined before the high performance liquid chromatography (HPLC) analysis. Quantitative analysis of all pigments was conducted using a Shimadzu HPLC system with a reverse phase column (Agilent Eclipse XDB-C8, 3.5 µm particle size, 150-mm length × 4.6-mm diameter).

Dissolved Nutrients
Nutrient analyses (Phosphorous, Ammonia, Nitrate+Nitrite) were performed on Lachat QuikChem 8500.

Instruments

CHN Elemental Analyzer

Supplied Name: Thermo FLASH 2000 CHN Elemental Analyzer

Supplied Description:

The organic carbon and nitrogen content of the samples was measured using a Thermo FLASH 2000 CHN Elemental Analyzer. Precision for the C/N content is within 5%.

Instrument Type

Generic Name: CHN Elemental Analyzer

Acronym: CHN_EA

Generic Description:

A CHN Elemental Analyzer is used for the determination of carbon, hydrogen, and nitrogen content in organic and other types of materials, including solids, liquids, volatile, and viscous samples.

High-Performance Liquid Chromatograph

Supplied Name: Shimadzu HPLC system

Supplied Description:

Shimadzu HPLC with reverse phase column was used for pigment analysis.
Reverse phase column was Agilent Eclipse XDB-C8, 3.5 µm particle size, 150-mm length × 4.6-mm diameter

Instrument Type

Generic Name: High-Performance Liquid Chromatograph

Acronym: HPLC

Community Identifier: http://vocab.nerc.ac.uk/collection/L05/current/LAB11/

Generic Description:

A High-performance liquid chromatograph (HPLC) is a type of liquid chromatography used to separate compounds that are dissolved in solution. HPLC instruments consist of a reservoir of the mobile phase, a pump, an injector, a separation column, and a detector. Compounds are separated by high pressure pumping of the sample mixture onto a column packed with microspheres coated with the stationary phase. The different components in the mixture pass through the column at different rates due to differences in their partitioning behavior between the mobile liquid phase and the stationary phase.

Isotope-ratio Mass Spectrometer

Supplied Name: Thermo Delta V Plus isotope ratio mass spectrometer

Supplied Description:

Stable carbon isotopes were measured with a Thermo Delta V Plus isotope ratio mass spectrometer (coupled from a Thermo FLASH 2000 CHN Elemental Analyzer). The δ13C values were expressed relative to Vienna Pee Dee Belemnite standard, with precision within 0.2%.

Instrument Type

Generic Name: Isotope-ratio Mass Spectrometer

Acronym: IR Mass Spec; IRMS

Community Identifier: http://vocab.nerc.ac.uk/collection/L05/current/LAB16/

Generic Description:

The Isotope-ratio Mass Spectrometer is a particular type of mass spectrometer used to measure the relative abundance of isotopes in a given sample (e.g. VG Prism II Isotope Ratio Mass-Spectrometer).

Nutrient Autoanalyzer

Supplied Name: Lachat QuikChem 8500

Supplied Description:

Instrument Type

Generic Name: Nutrient Autoanalyzer

Community Identifier: http://vocab.nerc.ac.uk/collection/L05/current/LAB04/

Generic Description:

Nutrient Autoanalyzer is a generic term used when specific type, make and model were not specified. In general, a Nutrient Autoanalyzer is an automated flow-thru system for doing nutrient analysis (nitrate, ammonium, orthophosphate, and silicate) on seawater samples.

YSI Sonde 6-Series

Supplied Name: YSI 600XLM Sonde

Supplied Description:

The YSI 600XLM is an economical logging system for long-term, in situ monitoring and profiling that measures eleven parameters simultaneously: DO (% and mg/L), ORP, Temperature, Depth or Level, Conductivity, Total Dissolved Solids, Specific Conductance, Resistivity, Salinity, and pH.

Instrument Type

Generic Name: YSI Sonde 6-Series

Community Identifier: http://vocab.nerc.ac.uk/collection/L22/current/TOOL0737/

Generic Description:

YSI 6-Series water quality sondes and sensors are instruments for environmental monitoring and long-term deployments. YSI datasondes accept multiple water quality sensors (i.e., they are multiparameter sondes). Sondes can measure temperature, conductivity, dissolved oxygen, depth, turbidity, and other water quality parameters. The 6-Series includes several models. More from YSI.
