Methods and Sampling: <p><strong>Methods &amp; Sampling:</strong></p>
<p>Samples were collected at 14 different sites quarterly from June 2017 through September 2018 in Galveston Bay and at 10 sites along the Texas coast in the Gulf of Mexico in June, August, and November of 2017 to investigate changes in water chemistry following Hurricane Harvey.</p>
<p>For cruises in Galveston Bay, discrete water samples were collected with a Niskin (General Oceanics) bottle at the surface (0.5 m) and ~1.2 m off the bottom. Samples collected for carbonate chemistry analysis (TA/DIC) were transferred from the Niskin to 250 mL narrow-mouth borosilicate glass bottles using a 0.2 mm polypropylene Whatman Polycap 36 Tissue Culture Grade (TC) in-line filter for total alkalinity (TA) and dissolved inorganic carbon (DIC) analysis, leaving approximately 5 mL headspace for thermal expansion. Some samples in September and November 2017 were collected using 0.2 mm Whatman Polycap 36 Aqueous Solution (AS) filters. However, no significant difference was found in the carbonate chemistry analysis for samples using either filter, therefore no distinction is made. Conductivity, temperature, and depth (CTD, SonTek Castaway™) profiles were conducted concurrently with Niskin samples at each station.&nbsp;Discrete water samples for TA/DIC on WTX cruises (WTX1/WTX2/WTX4) were collected using Niskin bottles (6L/6L/10L) on a Seabird CTD rosette. Carbonate chemistry water samples (TA/DIC) were collected similar to those from Galveston Bay, but no in-line filter was used.&nbsp;All TA/DIC samples was poisoned with 100 mL saturated mercuric chloride solution immediately after collection to inhibit biological activity, and then sealed with silicone-free type L Apiezon grease and ground glass stoppers with rubber bands and plastic clamps.&nbsp;TA and DIC were analyzed simultaneously on a Versatile INstrument for the Determination of Total inorganic carbon and titration Alkalinity (VINDTA) 3C in Dr. Kathryn Shamberger’s lab at Texas A&amp;M University. The VINDTA uses coulometric titration for DIC analysis and an open cell potentiometric titration for TA analysis.&nbsp;Dissolved inorganic nutrient samples from all fieldwork operations were transferred from the Niskins to a&nbsp;a polycarbonate flask&nbsp;using a GF/C 0.2 micron filter, frozen, and analyzed by the Geophysical Environmental Research Group at Texas A&amp;M University on an Astoria Analyzer.<br />

RAPID: The impact of increased fresh water input from Hurricane Harvey to the water quality and stratification of coastal and offshore waters of Texas.
https://osprey.bco-dmo.org/project/809503
RAPID: The impact of increased fresh water input from Hurricane Harvey to the water quality and stratification of coastal and offshore waters of Texas.
<p>In late August 2017, Category 4 Hurricane Harvey made landfall on Coastal Texas, 2017 and stalled bringing 125 cm of rain to Southeastern Texas over a five-day period resulting in catastrophic flooding along most of the Gulf coast of Texas as well as the metropolitan Houston area and 18 surrounding counties. Dams and reservoirs filled and even on September 1st ? 3rd releases from these dams continued to flood the area releasing even more water. Approximately 11 trillion gallons were estimated to have fallen and eventually this freshwater will be released onto the broad Texas continental shelf. In the US alone there has never been so much fresh water impacting a coastal area other than the discharge of the Mississippi River, which divides between the Atchafalaya River and the Birdfoot Delta to the east and injects freshwater into a much narrower shelf and into much deeper water in the north-central Gulf. The main hypothesis of the Rapid response project is that freshwater from Hurricane Harvey has 1) reduced coastal water quality by increasing stratification, and thereby inhibiting ventilation of atmospheric oxygen to sub-surface waters and 2) increased respiration by transporting nutrients from terrestrially derived sources leading to increased biomass and microbial activity. Secondly, the ocean heat content of the Texas Bight region contributed to the intensification of Hurricane Harvey by supplying thermal heat to the storm as it passed from the deep Gulf of Mexico to the shelf region. This project will provide critical information on how freshwater runoff from hurricane Harvey is impacting the stratification, oxygen, nutrient budgets of the coastal waters and whether this could lead to hypoxia and other long-term ecological impacts along the Texas shelf. The data will be made available rapidly to other researchers, students and the public.</p>
<p>This project aims to answer two questions of importance which could not be answered without a major flood. Is the freshwater from Hurricane Harvey reducing coastal water quality by increasing stratification, thereby inhibiting ventilation of atmospheric oxygen to subpycnocline water and is it increasing respiration by transporting nutrients from terrestrially derived sources leading to increased biomass and microbial activity? The project will also seek to determine if the ocean heat content of the Texas Bight region contributed to the intensification of Hurricane Harvey by supplying thermal heat to the storm as it passed from the deep Gulf of Mexico to the shelf region. This Rapid response project will conduct two research cruises on the R/V Pelican, one in late September and one in mid-November to quantify the effects and potential impacts of the freshwater run-off from Hurricane Harvey along the southern coast of Texas. In addition to the two cruises using a suite of oceanographic physio-chemical measurements, an autonomous Wave Glider will sample a grid to follow the freshwater plume and a buoyancy-controlled ocean glider will determine the depth and characteristics of the freshwater intrusion and its evolution between cruises and after data from two cruises in June and August 2017 prior to Hurricane Harvey. The research cruises will use existing offshore observing systems, i.e., the Texas Automated Buoy System, the Texas HF Radar network, and the Texas A&M University buoyancy-controlled glider program, to integrate the observations into a comprehensive picture of how the coastal region responded to the impulsive freshwater resulting from the unprecedented terrestrial flooding event in southeastern Texas.</p>

MARIANDA VINDTA 3C
PI Supplied Instrument Name: MARIANDA VINDTA 3C Instrument Name: MARIANDA VINDTA 3C total inorganic carbon and titration alkalinity analyser Instrument Short Name:inorganic carbon and alkalinity analyser Instrument Description: The Versatile INstrument for the Determination of Total inorganic carbon and titration Alkalinity (VINDTA) 3C is a laboratory alkalinity titration system combined with an extraction unit for coulometric titration, which simultaneously determines the alkalinity and dissolved inorganic carbon content of a sample. The sample transport is performed with peristaltic pumps and acid is added to the sample using a membrane pump. No pressurizing system is required and only one gas supply (nitrogen or dry and CO2-free air) is necessary. The system uses a Metrohm Titrino 719S, an ORION-Ross pH electrode and a Metrohm reference electrode. The burette, the pipette and the analysis cell have a water jacket around them. Precision is typically +/- 1 umol/kg for TA and/or DIC in open ocean water. Community Standard Description: http://vocab.nerc.ac.uk/collection/L22/current/TOOL0481/

Seabird CTD
PI Supplied Instrument Name: Seabird CTD PI Supplied Instrument Description:For WTX1 and WTX2: Sea-Bird SBE 25 CTD Instrument Name: Sea-Bird SBE 25 Sealogger CTD Instrument Short Name:CTD SBE 25 Instrument Description: The Sea-Bird SBE 25 SEALOGGER CTD is battery powered and is typically used to record data in memory, eliminating the need for a large vessel, electrical sea cable, and on-board computer. All SBE 25s can also operate in real-time, transmitting data via an opto-isolated RS-232 serial port. Temperature and conductivity are measured by the SBE 3F Temperature sensor and SBE 4 Conductivity sensor (same as those used on the premium SBE 9plus CTD). The SBE 25 also includes the SBE 5P (plastic) or 5T (titanium) Submersible Pump and TC Duct. The pump-controlled, TC-ducted flow configuration significantly reduces salinity spiking caused by ship heave, and in calm waters allows slower descent rates for improved resolution of water column features. Pressure is measured by the modular SBE 29 Temperature Compensated Strain-Gauge Pressure sensor (available in eight depth ranges to suit the operating depth requirement). The SBE 25's modular design makes it easy to configure in the field for a wide range of auxiliary sensors, including optional dissolved oxygen (SBE 43), pH (SBE 18 or SBE 27), fluorescence, transmissivity, PAR, and optical backscatter sensors.
