"POC: 500 mL seawater was filtered from depths above 100 m. One L seawater was
filtered for depths below 100 m. All seawater samples were filtered gently via
vacuum (<10 mm Hg) through 25 mm (0.7 \\u00b5m) Whatman GF/F filters that were
precombusted at 450\\u02daC for 4 hours. Filters were folded in quarters and
stored in pre-combusted (450\\u02daC for 4 h) glass scintillation vials.
Samples were stored at -20\\u02daC until analysis at the UC Santa Barbara
Marine Science Institute Analytical Lab on an Automated Organic Elemental
Analyzer following the Dumas combustion method.
 
Nutrients: 40 mL of seawater was directly filtered from the Niskin bottle
through a 0.8 \\u00b5m polycarbonate filter housed in a 47 mm polycarbonate
filter holder into a sterile 50 mL conical centrifuge tube. Samples were
stored at -20\\u02daC until analysis at the UC Santa Barbara Marine Science
Institute Analytical Lab via flow-injection analysis on a QuickChem 8500
Series 2.
 
HPLC: Approximately 2 L seawater was filtered through 25 mm (0.7 \\u00b5m)
Whatman GF/F filters. Filters were folded in half, stored in foil packets, and
put immediately in liquid nitrogen, where they were kept through shipment to
and until analysis at NASA Goddard Space Flight Center. HPLC pigments were
analyzed by Crystal Thomas following Van Heukelem and Thomas (2001):

"NSF Award Abstract:
Massive wildfires in coastal regions cause ash to fall into the ocean, with unknown impacts. Ash contains chemical elements and materials that can encourage the growth of microscopic organisms in the surface ocean. The Thomas Fire has burned over 240,000 acres in southern California since Dec 4, 2017. The winds have carried a plume of smoke, ash and soot more than 1000 km over the Santa Barbara Channel. The intellectual merit of this RAPID project focuses on the impact of fire ash supply to coastal ocean ecosystems, by studying the 2017 Thomas Fire. This is achieved through a combination of experiments and environmental measurements, including an oceanographic expedition to the affected area aboard the R/V Sally Ride. The broader impacts of this award include the shipboard training of more than twelve graduate students as well as providing insight as to effects of the Thomas Fire on the coastal ocean.
Massive wildfires can couple terrestrial ecosystems to coastal ocean ecosystems through depositional and runoff processes. The Thomas Fire, which began on Dec 4, 2017, has burned over 240,000 acres and the persistent offshore winds created a plume of smoke, ash and soot that extended over 1000 km off shore. This unfortunate circumstance provides an opportunity to investigate the impact of ash deposition on the coastal ocean. This research entails a series of incubation experiments and measurements designed to assess the impact of fire ash deposition on the biogeochemistry of the coastal ocean. Specifically, the research tests the hypothesis that the deposition of wildfire-derived particulate matter to the coastal ocean impacts the planktonic communities of the upper water column, providing nutrients that facilitate blooms of phytoplankton, leaching dissolved organic carbon to surface waters that feeds heterotrophic bacterial populations, and serving as a source of sinking particulate matter that feeds heterotrophic bacterial populations deeper in the water column. These hypotheses are tested through a series of experiments at sea and in the home laboratories, and through shipboard measurements and analysis of samples collected from impacted waters.";

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 (external link) Data Access Protocol (DAP) (external link) and its selection constraints (external link).

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.

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.
