IOOS Sensor Observation Service (SOS) Server for NANOOS, the Northwest Association of Networked Ocean Observing Systems (http://nanoos.org). Provides access to marine in-situ observation data for the US Pacific Northwest and lower British Columbia, from the NANOOS asset data store harvested and integrated by NVS (NANOOS Visualization System, http://nvs.nanoos.org). To avoid data duplication, currently only assets not otherwise available to the IOOS Catalog (http://catalog.ioos.us) are accessible through this SOS server; for example, assets from most federal agencies are not accessible on this server, but they are available on the NVS application. This NANOOS service is run by the 52North IOOS SOS server software, and complies with the IOOS SOS "Milestone 1" service profile (https://code.google.com/p/ioostech/wiki/SOSGuidelines). This station provides the following variables: Air temperature, Sea water salinity, Sea water temperature, Surface air pressure, Surface partial pressure of carbon dioxide in air, Surface partial pressure of carbon dioxide in sea water, Wind from direction, Wind speed

Timeseries data from 'Humboldt Bay Burke-O-Lator' (humboldt-bay-burkeolator)

This dataset includes continuous sea surface measurements of dissolved inorganic carbon (DIC), calculated total alkalinity, pH on NBS scale, calculated partial pressure of carbon dioxide (pCO2), temperature, salinity and dissolved oxygen during a small fishing boat cruises in Jiaozhou Bay, Yellow Sea, from 2018-04-25 to 2018-08-03. The data were collected using a Van Dorn water sampler aboard a small fishing vessel. At each station, just surface samples were collected since water column is vertically well mixed. The measurements were done under project named "Effects of biological processes on calcium carbonate saturation in eutrophic coastal oceans: a case study in Jiaozhou Bay", The project is funded by Basic Scientific Fund for National Public Research Institutes of China (2016Q01, 2019S05).

This dataset consists of surface measurements of partial pressure of CO2 (pCO2), pH on total scale, water temperature, salinity, and other variables in the Casco Bay, Gulf of Maine from 2015-04-23 to 2020-06-12. The central goal of this project was to install continuous monitoring sensors in Casco Bay to measure ocean and coastal acidification parameters at high temporal resolution. The system was installed at the Southern Maine Community College (SMCC) pier in South Portland, Maine. The pier is located in the Portland Channel, an important southern outlet of Casco Bay, and near outlets of the Fore and Presumpscot rivers in a relatively urban area of Casco Bay. This location was selected because it is nearshore, accessible, and has historic nutrient data collected by the Friends of Casco Bay. Sensors for temperature/conductivity/salinity, dissolved oxygen, pH and pCO2 were mounted to a ‘lander’ frame, which was lowered via davit to the bottom. Sensor data were thus collected approximately 1m from the bottom, and at varying depth depending on the tide.

Timeseries data from 'Hog Island Oyster' (hog-island-hatchery)

This dataset consists of carbonate chemistry discrete profile data collected on two of the Northeast US Coast Shelf LTER cruises, EN617 and EN627 summer 2018 and winter 2019. The dataset includes in situ temperature, salinity, and dissolved oxygen as measured from a CTD, and also includes discrete samples for dissolved inorganic carbon and total alkalinity.

Timeseries data from 'Tiburon CO2 BOB Mooring' (tiburon-co2)

Timeseries data from 'Exploratorium (pCO2 Buoy)' (exploratorium-pco2-buoy)

This dataset consists of discrete profile data collected data small ships near the California Current Ecosystem (CCE) mooring in the North pacific Ocean from 2015-11-17 to 2021-06-18. California Current Ecosystem moorings (CCE1 and CCE2) are surface buoys equipped with interdisciplinary scientific sensors including surface water and air pCO2, meteorological sensors (wind, air temperature, humidity, and air pressure), sea water temperature, salinity, currents, dissolved oxygen, pH, nutrients, and chlorophyll fluorescence. CCE1 is located offshore in the core of the California Current (CalCOFI station 80.80), and CCE2 is closer to shore on the shelf break near Point Conception (CalCOFI station 80.55). CCE moorings measure physical, biological, and chemical variables with temporal resolutions high enough to resolve event-scale phenomena, and transmit real-time data to shore. Annual cruises are conducted to recover and the moorings. During these cruises, CTD casts are performed with water samples of salinity, dissolved oxygen, dissolved inorganic carbon, total alkalinity, nutrients (nitrite, nitrate, silicate, phosphate, and ammonium), chlorophyll-a, and phaeopigment. This data file reports the discrete water sample results as well as CTD temperature and salinity values where the bottle samples were taken.

This dataset contains the seawater chemistry monthly means with standard deviations measured using water samples collected at the Mukilteo Research Station located in the Puget Sound, WA from 2018-08-26 to 2019-07-11. Water temperature (°C) is from the average of all 4 Durafet pH sensors deployed in the experimental tanks. Salinity data are from periodic measurements taken of all 6 experimental tanks use a hand-held Orion salinity sensor. The ambient and high-CO2 pH values are spectrophotometric pH averages from all treatment tanks. Alkalinity was calculated from the salinity values using the functional relationship in (Trigg et al., 2019). The pCO2 and calcite saturation state values were calculated using the SeaCarb R package (Gattuso et al., 2021) with the spectrophotometric pH and calculated alkalinity values as carbonate system parameter inputs. No spectrophotometric pH or Orion salinity data were recorded for January because a U.S. Government shutdown prevented collection of these data. However, automated pH and salinity sensors operating in the experimental tanks during January indicate that interpolation by averaged data from December and February, is a reasonable approximation.
