The hydrographic sampling performed by OOI-CGSN (the Ocean Observatories Initiative - Coastal and Global Scale Nodes) part of each Array turn represents a significant collection of valuable physical, chemical, and biological information. In addition to the CTD, collected hydrographic data include discrete oxygen, salinity, nutrient (nitrate, nitrite, silicate, phosphate, ammonium), chlorophyll, and carbon system measurements. These data serve several important functions. First, they are necessary for the calibration and evaluation of the moored instrumentation at each Array. Furthermore, the annual (Global) or biannual (Coastal) collection of data at the same locations provides a unique time series of a large set of water properties following established community standards and methods, independent of its association with the OOI moorings. The analyses of collected water samples for the parameters listed above are performed by a number of outside labs on behalf of OOI-CGSN. Consequently, the water sampling data for a given cruise is distributed among a number of different files. The Discrete Sampling Summary integrates the related CTD, metadata, and discrete water sample data into a single file. Additionally, it synthesizes qualitative and quantitative information about the quality of a measurement into data quality flags for each associated parameter which follow WOCE-standards. The final product is the Discrete Sampling Summary spreadsheet which contains the metadata, CTD data and discrete water sample data into a single spreadsheet with data quality flags. This dataset includes hydrographic data from the Global Southern Ocean Array. The Global Southern Ocean Array was located in the high-latitude South Pacific, west of the Southern tip of Chile in an area of large scale thermohaline circulation, intermediate water formation , and CO2 sequestration. It permitted examination of linkages between the Southern Ocean and the Antarctic, including strengthening westerly winds and upwelling. This array was in place from February 2015 to January 2020 when it was removed.

OOI Global Station Papa Array CTD and Discrete Water Sampling Data from Mooring Overturning Cruises in the Gulf of Alaska from 2013 to 2023 (OOI Cruise Data project)
Abstract: The hydrographic sampling performed by OOI-CGSN (the Ocean Observatories Initiative - Coastal and Global Scale Nodes) as part of each Array turn represents a significant collection of valuable physical, chemical, and biological information.

This dataset includes hydrographic data from the Global Station Papa Array located in the Gulf of Alaska next to the NOAA Pacific Marine Environmental Laboratory (PMEL) Surface Buoy. The region is extremely vulnerable to ocean acidification, has a productive fishery, and low eddy variability. It is impacted by the Pacific Decadal Oscillation and adds to a broader suite of OOI and other observatory sites in the Northeast Pacific.

This dataset includes hydrographic data from the Global Argentine Basin Array, which was located in the South Atlantic from March 2015 to January 2018. The Argentine Basin Array was useful for exploring the global carbon cycle because of its high biological productivity fueled by iron-laden dust from South America. With strong currents persisting on the seafloor and water mass mixing, this region has elevated levels of eddy kinetic energy similar to those in the Gulf Stream.more » « less

It is one of the few places on Earth with deep-water formation that feeds the large-scale thermohaline circulation.more » « less

The Coastal Pioneer New England Shelf (NES) Array was located off the coast of New England, about 75 nautical miles south of Martha’s Vineyard from 2013 to 2022. The Continental Shelf-Slope area in this region is highly productive. It serves as a dynamic intersection where ocean currents meet in weather-like “fronts,” and where nutrients, pollutants, and other properties are exchanged between the coast and the deep ocean. Data from the inshore, shelf area helps to examine exchanges between the shelf and slope and the shelf ecosystem, as well as to provide broader insight into air-sea gas exchange, including carbon dioxide absorption.The seven-site mooring array spans along- and across-shelf distances of 9 km and 47 kilometers (km). Mooring sites are separated from each other by distances of 9.2 km to 17.5 km.more » « less

This dataset contains bottle-calibrated dissolved oxygen (DO) profiles collected from Conductivity Temperature Depth (CTD) casts on turn-around cruises performed yearly to maintain the Ocean Observations Initiative (OOI) Global Irminger Sea Array (60.46°N, 38.44°W). DO profiles were used in conjunction with oxygen bottle measurements (Winklers) to produce a post-cruise oxygen-calibrated CTD product for scientific use. Bottle-calibrated CTD salinity products were used to produce post-cruise oxygen-calibrated CTD profiles starting in 2018 (Year 5). This document contains overviews of CTD data collection and processing and post-processing oxygen sensor calibration method. Reports for each cruise include a summary of relevant cruise events, oxygen sensor calibration results, and issues/problems associated with oxygen data collected on each cruise. This dataset has been created for end-users that require field-calibrated oxygen data products that are currently not provided by OOI through its standard data dissemination.more » « less
