This data set consists of 3,244 gridded, daily averaged temperature, practical salinity, potential density, and dissolved oxygen profiles. These profiles were collected from October 2014 to May 2025 by the NSF Ocean Observatories Initiative Washington Offshore Profiler Mooring (CE09OSPM) located at 46.8517°N, 124.982°W between approximately 35 and 510 meters water depth using a McLane® Moored Profiler (MMP). The MMP was equipped with a Sea-Bird Scientific 52-MP (SBE 52-MP) CTD instrument and an associated Sea-Bird Scientific (SBE 43F) dissolved oxygen sensor. Raw binary data files [C*.DAT (CTD data); E*.DAT (engineering data plus auxiliary sensor data) and A*.DAT (current meter data)] were converted to ASCII text files using the McLane® Research Laboratories, Inc. Profile Unpacker v3.10 application. Dissolved oxygen calibration files for each of the twenty deployments were downloaded from the Ocean Observatories Initiative asset-management GitHub® repository.  The unpacked C*.TXT (CTD data); E*.TXT (engineering data plus auxiliary sensors) and A*.TXT (current meter data) ASCII data files associated with each deployment were processed using a MATLAB® toolbox that was specifically created to process OOI MMP data. The toolbox imports MMP A*.TXT, C*.TXT, and E*.TXT data files, and applies the necessary calibration coefficients and data corrections, including adjusting for thermal-lag, flow, and sensor time constant effects. mmp_toolbox calculates dissolved oxygen concentration using the methods described in Owens and Millard (1985) and Garcia and Gordon (1992). Practical salinity and potential density are derived using the Gibbs-SeaWater Oceanographic Toolbox. After the corrections and calculations for each profile are complete, the data are binned in space to create a final, 0.5-dbar binned data set. The more than 24,000 individual temperature, practical salinity, pressure, potential density, and dissolved oxygen profiles were temporally averaged to form the final, daily averaged data set presented here. Using the methods described in Risien et al. (2023), daily temperature, practical salinity, potential density, and dissolved oxygen climatologies were calculated for each 0.5-dbar depth bin using a three-harmonic fit (1, 2, and 3 cycles per year) based on the 10-year period January 2015 to December 2024. 

"10-minute and hourly measurements of surface weather observations collected by the OOI Coastal Endurance Array using the ASIMET meteorological sensor suite measuring (among other variables) the sea surface temperature, salinity and wind speed. This data has been re-processed from source data available on the OOI Gold Copy THREDDS catalog.\n\n10-minute and hourly averaged datasets are created from the 1-minute data produced by the ASIMET system to create data records with automated and human-in-the-loop (HITL) quality control flags applied. In this version of the dataset (v1.0.1), only the sea surface temperature, salinity and wind speed data has been fully QC'd.\n\nThe wind records in these datasets are corrected for known underspeeding noted in the OOI Data Explorer annotations.  Based on comparisons to the OOI direct covariance flux wind measurements, the wind records presented in these datasets are adjusted upwards by a gain factor of 1.1236.\n\nNote, the data record is gappy in time; if no data was available for any of the sensors, then that timestamp was not included.\n\nData is organized in both NetCDF and Zarr files (in Zarr ZipStores) per mooring location differentiated by the file contents:\n\n\n\n\nMooring Location\nPer Deployment (NetCDF only)\nContinuous (NetCDF and Zarr)\n\n\n\n\n\n\nOregon Shelf Surface Mooring (80 m site depth)\n\n\n\nCE02SHSM-SBD11-06-METBKA000.10minute.per_deployment.nc\n\nCE02SHSM-SBD11-06-METBKA000.hourly.per_deployment.nc\n\n\n\nCE02SHSM-SBD11-06-METBKA000.10minute.continuous.nc\n\nCE02SHSM-SBD11-06-METBKA000.10minute.continuous.zarr.zip\n\nCE02SHSM-SBD11-06-METBKA000.hourly.continuous.nc\n\nCE02SHSM-SBD11-06-METBKA000.hourly.continuous.zarr.zip\n\n\n\nOregon Offshore Surface Mooring (572 m site depth)\n\n\nCE04OSSM-SBD11-06-METBKA000.10minute.per_deployment.nc\n\nCE04OSSM-SBD11-06-METBKA000.hourly.per_deployment.nc\n\n\n\nCE04OSSM-SBD11-06-METBKA000.10minute.continuous.nc\n\nCE04OSSM-SBD11-06-METBKA000.10minute.continuous.zarr.zip\n\nCE04OSSM-SBD11-06-METBKA000.hourly.continuous.nc\n\nCE04OSSM-SBD11-06-METBKA000.hourly.continuous.zarr.zip\n\n\n\n\n\nWashington Shelf Surface Mooring (87 m site depth)\n\n\n\nCE07SHSM-SBD11-06-METBKA000.10minute.per_deployment.nc\n\nCE07SHSM-SBD11-06-METBKA000.hourly.per_deployment.nc\n\n\n\nCE07SHSM-SBD11-06-METBKA000.10minute.continuous.nc\n\nCE07SHSM-SBD11-06-METBKA000.10minute.continuous.zarr.zip\n\nCE07SHSM-SBD11-06-METBKA000.hourly.continuous.nc\n\nCE07SHSM-SBD11-06-METBKA000.hourly.continuous.zarr.zip\n\n\n\nWashington Offshore Surface Mooring (542 m site depth)\n\n\nCE09OSSM-SBD11-06-METBKA000.10minute.per_deployment.nc\n\nCE09OSSM-SBD11-06-METBKA000.hourly.per_deployment.nc\n\n\n\nCE09OSSM-SBD11-06-METBKA000.10minute.continuous.nc\n\nCE09OSSM-SBD11-06-METBKA000.10minute.continuous.zarr.zip\n\nCE09OSSM-SBD11-06-METBKA000.hourly.continuous.nc\n\nCE09OSSM-SBD11-06-METBKA000.hourly.continuous.zarr.zip\n\n\n\n\n\nIn the 'per_deployment' files, data from overlapping deployments is made available for researchers wishing to assess the data on a per deployment basis.

A potential downside to these files is the time record is not monotonic, which may cause some issues depending on how the data is analyzed. These files are only available in NetCDF format. For those wishing to work with monotonic time records, the overlapping deployment data has been averaged and the deployment variable has been dropped. These 'continuous' files are available in both NetCDF and Zarr format (as Zarr ZipStores).\n\nThe hourly, 'per_deployment' data files are used as part of the processing of the PCO2A data available in 10.5281/zenodo.17883448.\n\n\n\n\nVersion\nPublication Date\nComments\n\n\nv1.0.0\n2025-12-16\nOriginal dataset.\n\n\nv1.0.1\n2025-12-17\n\n\nCorrected error in the creation of the 10-minute continuous records and updated both the NetCDF and Zarr files 10-minute continuous files for all moorings." 

Ocean boundary currents are complex and highly variable systems that play key roles in connecting the open and coastal ocean through cross-slope circulation and upwelling of nutrient-rich water. The structure, strength, and variability of boundary currents are associated with a broad range of spatial and temporal scales. For that reason, long-term boundary current monitoring is challenging and requires the use of complementary observing platforms and sensors coupled with numerical simulations. The Ocean Observations Physics and Climate Panel Boundary Systems Task Team recently held a virtual dialogue series to discuss six mature boundary current monitoring systems. The goal of the series was to examine strategies for developing a conceptual design for sustained observing activities applicable to a wide range of boundary current systems. This article provides a brief overview of the six systems, including users and the observational and modeling components needed to achieve scientific, operational, and societal goals. Ocean observing best practices and recommendations are shared to provide guidance for the coordination and sustainability of observing systems at ocean boundaries and to strengthen and integrate partnerships across and within the global observing networks.
