Abstract
To our knowledge, the FHL Ocean Observatory serves as the only multi-sensor array (~2 m from the surface) in the San Juan Islands archipelago that monitors for temperature, salinity, pH(total), carbon dioxide, dissolved oxygen, chlorophyll concentration, turbidity, and current velocity. In addition to the suite of ocean properties listed above, we also monitor the microplanktonic community using a camera system called the Imaging FlowCytoBot (IFCB). The IFCB is an automated imaging flow cytometer that is designed for the continuous monitoring of phytoplankton and microzooplankton. Using a laser-triggered, high-resolution camera, the IFCB generates images and optical data of individual plankton and other particles in the size range of >10-150 mm. Data produced by this project may be of interest to chemical and biological oceanographers, and climate scientists interested in the role of biogeochemistry in the global/regional climate system. This dataset includes pH, pCO2, temperature, salinity, and dissolved oxygen data recorded from 2018-2021.

Dataset Description

pH, pCO2, temperature, salinity, and dissolved oxygen data were recorded from 2018-2021 from a sensor array at Friday Harbor Laboratories Ocean Observatory (FHLOO).


Acquisition Description

Data are collected from a sensor array deployed at a floating dock at ~2-3 m water depth located at the University of Washington Friday Harbor Laboratories, Friday Harbor, WA (Lat = 48.5461, Long = -123.007). Sensors include: Sea-Bird SBE37 (temperature and salinity), Sunburst SAMI-pH (pH and temperature), Sunburst SAMI-pCO2 (pCO2 and temperature), Aanderaa Oxygen Optode 4351A (dissolved oxygen and temperature).

Data gaps (dates where instrument malfunctioned or was being serviced and there is no data) are reported in the supplemental file "FHLOO v2 Data Gaps" (PDF).


Processing Description

BCO-DMO Processing:
Version 1 (date 2020-10-15):

- converted date/time fields to ISO8601 format;
- added latitude and longitude as columns; values originally provided in dataset metadata.
- dataset history: note these data were originally provided as four separate datasets (listed under Related Datasets); those data have been corrected/updated by the project investigators and combined into one dataset. This is the version recommended for re-use.

Version 2 (date 2022-10-25):
- replaced previous version with version 2, which includes the following changes:
-- addition of new data added spanning 2021-05-07 to 2022-12-31;
-- "-9999" NA strings were changed to "nd";
-- the dataset has been filtered according to the data gap summary so that unreliable data (fouled sensors) are no longer included.
- BCO-DMO edits on this version include:
-- changed all dates to ISO8601 format;
-- replaced "NA" with "nd";
-- removed unnecessary columns.

Instruments

Dataset-specific Instrument Name
Sea-Bird SBE37
Generic Instrument Name
CTD Sea-Bird MicroCAT 37
Dataset-specific Description
Sea-Bird SBE37 (temperature and salinity)
Generic Instrument Description
The Sea-Bird MicroCAT CTD unit is a high-accuracy conductivity and temperature recorder based on the Sea-Bird SBE 37 MicroCAT series of products. It can be configured with optional pressure sensor, internal batteries, memory, built-in Inductive Modem, integral Pump, and/or SBE-43 Integrated Dissolved Oxygen sensor. Constructed of titanium and other non-corroding materials for long life with minimal maintenance, the MicroCAT is designed for long duration on moorings. In a typical mooring, a modem module housed in the buoy communicates with underwater instruments and is interfaced to a computer or data logger via serial port. The computer or data logger is programmed to poll each instrument on the mooring for its data, and send the data to a telemetry transmitter (satellite link, cell phone, RF modem, etc.). The MicroCAT saves data in memory for upload after recovery, providing a data backup if real-time telemetry is interrupted.

Dataset-specific Instrument Name
Sunburst SAMI-pCO2
Generic Instrument Name
Submersible Autonomous Moored Instrument
Dataset-specific Description
Sunburst SAMI-pCO2 (pCO2 and temperature)
Generic Instrument Description
The Submersible Autonomous Moored Instrument (SAMI) measures and logs levels of dissolved chemicals in sea and fresh water. It is a plastic cylinder about 6 inches wide and 2 feet long that is self-powered and capable of hourly measurements for up to one year. All data collected are logged to an internal memory chip to be downloaded later. SAMI sensors usually are placed a few feet underwater on permanent moorings, while others on floating drifters sample the water wherever the wind and currents carry them. The instruments have been used by researchers around the globe in a variety of studies since 1999. Dr. Mike DeGrandpre, University of Montana, developed the SAMI between 1990 and 1993 during his postdoctoral work at the Woods Hole Oceanographic Institution (Woods Hole, MA, USA).

Project Information

FSML: Instrumentation at UW Friday Harbor Laboratories for Studies of the Biological Impacts of Ocean Acidification and Ocean Change (FHLOO)

Coverage: University of Washington Friday Harbor Laboratories, Friday Harbor WA


Ocean change, including ocean acidification (OA), poses an unprecedented threat to oceanic and coastal ecosystems and to the societies that depend on them. The scale and complexity of the OA problem requires new spatially distributed data collection, and an integrated programmatic approach to OA research. The Salish Sea region, fed by waters of the Northeast Pacific, is particularly vulnerable to OA events associated with ocean upwelling and is already experiencing pH ranges that other areas will not see for many decades; commercial fisheries and shellfish aquaculture already appear to be affected or at risk. OA is further complicated in estuaries such as the Salish Sea by local processes including respiration, production, anoxia, and mixing, resulting in wide pH and pCO2 variation in time and space. Long-range plans for ocean change research at FHL focus on integrated ocean carbonate system observations, utilizing new advances in the development of ocean sensors and instruments, and incorporating biological response studies under laboratory and field conditions. Field conditions will be simulated using environmental and ecosystem modeling studies, and our findings will provide information for assessment of policy, and socio-economic responses.

Societal needs will be fully integrated with our research, merging the relevance of the problem and the need for human adaptation to OA. FHL will engage in knowledge transfer, with data and information flowing to and from policy makers, affected communities, scientists, and the general public. The shellfish aquaculture community will benefit economically from the new data and tribal governments will accrue benefits that could help sustain traditional food sources. The public will benefit through targeted education activities that improve general understanding of ocean processes and especially ocean acidification. UW and FHL will train a workforce that is ready to discover and deal with the impacts of OA and to realize adaptive responses that will allow affected industries and communities to thrive in the presence of this threat. Users include groups engaged in marine resource-based economies, members of coastal tribes, managers of marine resources, researchers in academic and government laboratories, and both formal and informal educators. FHL education programs reach broadly, from high school teachers and their students to undergraduate and graduate students and postdoctoral researchers. At the graduate level, FHL will prepare students for careers inside and outside of academia. Under represented minorities (URM) are fully integrated into FHL activities, with the objective of increasing their representation in oceanography, biology, fisheries and other OA and ocean-related fields. We will leverage existing programs (UW IGERT in Ocean Change, FHL Blinks and REU site programs, FHL Research Apprenticeships, NSF BEACON at UW) and create new programs to recruit, mentor, and prepare a community of URM students both on and off the university campus. We will expand our ongoing engagement of Native American students in ocean change research and education, near their own college campus (NWIC) and with their own instructors, in a culturally respectful way.
