"Nutrient Analysis Equipment and Techniques:
 
Nutrient samples were collected,\\u00a0filtered (0.2 \\u00b5m Acropak-200
polyethersulfone filters, Pall) and frozen on board until analysis on shore up
to 3 months later. Nutrient analyses (phosphate, silicate, nitrate+nitrite,
nitrite, ammonium, and urea) were performed on a 6-channel Astoria-Pacific
autoanalyzer using standard methods (WHPO 1994). Ammonia analyses were based
on Solorzano (1969), using phenol/hypochlorite in alkaline medium with a
sodium nitroprusside catalyst. Urea analyses were based on Aminot and Kerouel
(1982) using diacetyl monoxime in acid solution.
 
Dissolved Oxygen Analysis Equipment and Techniques:
 
Samples were collected for dissolved oxygen analyses soon after the rosette
was brought on board. Using a Tygon or silicone drawing tube, nominal 125 ml
volume-calibrated iodine flasks were rinsed 3 times with minimal agitation,
then filled and allowed to overflow for at least 3 flask volumes. Reagents
(MnCl2 then NaI/NaOH) were added to fix the oxygen before stoppering. The
flasks were shaken twice (> 1-minute inversions) to assure thorough dispersion
of the precipitate. The lip of the flask stopper was filled with ultrapure
water to prevent access to atmospheric oxygen during the up to 3 hours between
sample collection and analysis.
 
Oxygen flask volumes were determined gravimetrically to determine flask
volumes at TAMU Geochemical and Environmental Research Group (GERG). This is
done once before using flasks for the first time and periodically thereafter
when a suspect volume is detected.
 
Dissolved oxygen analyses were performed with an automated Winkler oxygen
titrator (Langdon Enterprises, Miami) using amperometric end-point detection.
Thiosulfate (nominally 0.01 N) was standardized against 0.01 N potassium
iodate prior to sample analysis.
 
Salinity Analysis Equipment and Techniques:
 
Salinity samples were drawn into 200 mL Kimax high-alumina borosilicate
bottles, which were rinsed three times with sample prior to filling to the
shoulder. The bottles were sealed with plastic insert thimbles to reduce
evaporation. PSS78 salinity (UNESCO 1981) was calculated for each sample from
the measured conductivity ratios.
 
A Guildline Autosal 8400B salinometer (S/N 65715) was used for
salinity/conductivity measurements. The salinity analyses were performed after
samples had equilibrated to laboratory temperature, usually within 6 weeks
after collection. The salinometer was standardized for each group of analyses
using OSIL standard seawater, with frequent use of a secondary deep water
standard to check for drift during runs.";

"This project was recently funded by NSF award OCE-1760620. More information will be added as it becomes available.
Project summary from NSF RAPID proposal:Overview: Tropical cyclones (hurricanes and tropical storms) can produce substantial impacts in marine ecosystems, including alteration of tidal regimes, upwelling, vertical mixing, sediment resuspension, and terrestrial runoff that affect estuaries, coastal areas and the open ocean. The drastic perturbations following tropical cyclones have also been shown to produce immediate shifts in phytoplankton community composition. High temporal resolution observations from the Imaging FlowCytobot (IFCB) revealed that hurricanes in the Gulf of Mexico (GOM) initially caused blooms of diatoms, which subsequently were replaced by blooms of dinoflagellates. This change in the community structure was hypothesized to be related to the ability of dinoflagellates compared to diatoms to assimilate organic nitrogen compounds supplied by the high river discharge that resulted from the rainfall. This RAPID project will address two hypotheses:
1. Community structure will be a flagellate-dominated system as long as the high river discharge continues. Community structure will shift to a diatom-dominated system when environmental conditions return to normal. Continuous, high temporal resolution data from the IFCB time series will provide estimates of abundance and biovolume to assess the temporal variability of phytoplankton from the aftermath of the hurricane until the return to normal conditions.
2. Nitrogen will be the main driver of shifts in community metabolic responses.
Analysis of gene expression profiles, environmental conditions, and water quality parameters will provide a time series of metabolic functional responses. Metatranscriptomic analysis may also provide insight into taxa-specific metabolic responses related to nutrient and other environmental stresses as a consequence of Hurricane Harvey.
We propose two rapid response cruises to sample at 5 sites along a transect from Galveston to Port Aransas. At each station, CTD profiles and water samples from surface and the chlorophyll maximum for nutrient and carbonate chemistry analysis and RNA sequencing will be collected. Concurrently, the IFCB will operate continuously onboard for comparison with the ongoing time series at Surfside Beach. If the water column is strongly stratified, samples will be collected at the low salinity surface layer and the high salinity deeper layer. Time series analyses of the response of the phytoplankton community will include high frequency data of physical and hydrological variables, water quality measurements, and metatranscriptome analyses. Results will provide novel insights on the impact that extreme hurricanes exert on the phytoplankton community and ultimately in ecosystem functioning and resilience.
Intellectual Merit: Hurricane Harvey is the strongest hurricane to hit the GOM in decades; therefore, the impact of this hurricane on the phytoplankton community may be unprecedented in terms of response and duration. It is unknown how the phytoplankton community will respond and the time to return to \"normal\" condition. Immediate high temporal resolution sampling is the only way to fully capture the effects of tropical cyclones on coastal phytoplankton communities. And, in combination with metatranscriptomic analysis, the time series of metabolic responses can be elucidated.
Broader Impacts: If extreme storms are predicted to increase with future climate change, the taxa-specific responses provided by the IFCB time series are tremendously valuable for detecting changes, which have implications for ecosystem functioning. Over the past decade, the high temporal resolution phytoplankton time series at TOAST has proven to be invaluable in providing early warning for 8 harmful algal blooms. Given the unknown impact of Hurricane Harvey on the Texas coast (or the duration of the impact), the IFCB time series are invaluable to resource managers. Time series data have been successfully implemented into undergraduate Oceanography laboratory courses at TAMU to teach the value of ocean observing and assessment to the students' lives. Data from this Hurricane Harvey rapid response will also be included in future problem sets for students. As a strategy for targeting general audiences, outcomes of this project will also be produced for \"On the Ocean\", a weekly radio program on KAMU, the public radio station on TAMU campus; podcasts are also archived linked to the Oceanography department's website.

Using tabledap to Request Data and Graphs from Tabular Datasets

tabledap lets you request a data subset, a graph, or a map from a tabular dataset (for example, buoy data), via a specially formed URL. tabledap uses the OPeNDAP Data Access Protocol (DAP) and its selection constraints.

The URL specifies what you want: the dataset, a description of the graph or the subset of the data, and the file type for the response.

• (easy) You can get data by using the dataset's Data Access Form or Subset form. They make the URL for you.
• (easy) You can make a graph or map by using the dataset's Make A Graph form. It makes the URL for you.
• (not hard) You can bypass the forms and get the data or make a graph or map by generating the URL by hand or with a computer program or script.

Tabledap request URLs must be in the form
https://coastwatch.pfeg.noaa.gov/erddap/tabledap/datasetID.fileType{?query}
For example,
https://coastwatch.pfeg.noaa.gov/erddap/tabledap/pmelTaoDySst.htmlTable?longitude,latitude,time,station,wmo_platform_code,T_25&time>=2015-05-23T12:00:00Z&time<=2015-05-31T12:00:00Z
Thus, the query is often a comma-separated list of desired variable names, followed by a collection of constraints (e.g., variable<value), each preceded by '&' (which is interpreted as "AND").

For details, see the tabledap Documentation.
