Surface water temperature measured at 30-minute sampling intervals from the years 2000 to 2023 at Tatoosh Island, Washington, USA

Abstract:

This dataset reports observations of surface water temperatures at 30-minute sampling intervals from the year 2000 to the present (2023) from Tatoosh Island, Washington, USA. Data were collected by Tim Wootton and Cathy Pfister, University of Chicago. Observations prior to May 2011 were generated during the growing season (typically late April to early September) using Hydrolab DataSondes, whereas subsequent observations were generated all year using primarily HOBO Pendant temperature/light loggers, supplemented with measurements derived from HOBO conductivity/salinity/temperature logger or Hydrolab DataSondes. These temperatures may be useful for detecting marine heat waves or other temperature anomalies, and for documenting surface temperature dynamics across daily, seasonal, and decadal scales.

Description

Notes about use of this dataset:
There are no restrictions on access to this dataset. Acknowledgment of the Makah Tribal Council for permission to allow these data to be collected on their lands should be made where possible when the data are an essential part of the publication.

These data series are being actively extended and analyzed by the data provider, and interested investigators may wish to contact the data provider regarding these data, the ecological context under which these data were collected, whether planned use of these data represents redundant efforts, and any details of the data collection process the data provider may have inadvertently neglected to include here. As a rule of thumb for any data made publicly available, including these, investigators intending to use these data for publication should consider the considerable effort made to gather and organize them, and whether publication would reasonably be possible without including these data. If not, then it may be appropriate to explore involving the author in the publication process.

Methods & Sampling

Data loggers were deployed in a large tide pool (Lat N 48° 23.643', Long W 124° 44.149') approximately 1 meter (m) below its lip, which is located at 0.8 m MLLW. The pool is isolated at tidal levels below this value (ignoring waves) and connected to the eastern Pacific Ocean above this tidal level. Data were generally taken at 30-minute intervals. Before 2011, data were only collected during our summer field season (April-September, depending on year). From 16 May 2011 onward, data were taken nearly continuously, except when the pool was drained to service equipment.

Study location:
Tatoosh Island, Washington, USA. Intertidal/nearshore temperate waters. Depth varies with the tides as the instruments are fixed to the bottom. Data are from an intensively sampled large (>5000 liter) tide pool that is both accessible for servicing during the lowest low tides and allows equipment to be safely installed and remain underwater. The lowest lip of the pool is at 0.8 m MLLW, and equipment is deployed about 1 m below the lip. At tide heights > 0.8 m, the pool is connected to the eastern Pacific Ocean just outside the mouth of the Strait of Juan de Fuca.

Instruments:
Prior to May 2011, data were collected using Hydrolab DataSondes with factory-calibrated settings (OTT-Hydromet, Loveland, Colorado, USA). After this date, the data here were largely taken from 1-2 HOBO Pendant Temperature/Light (UA-002-64) loggers with factory-calibrated settings (Onset Computer, Bourne, Massachusetts, USA). Occasionally, HOBO Pendants were not deployed in this interval, in which case alternative platforms generated the data: Hydrolab DS5x DataSonde (16 May 2011-29 August 2011, 6 April 2012-19 August 2012, 29 May 2014-7 August 2014, 28 April 2021-11 June 2021) or HOBO Conductivity/Salinity data logger (U24-002-C; Onset Computer; 17 August 2012-27 April 2013, 1 September 2016-27 April 2017). All units were attached to the side wall (approximately vertical) of the tide pool using stainless steel hardware and Rawl masonry plugs.

Known Problems or Issues:
There are sampling gaps in fall-winters of 2000-2011 and for several hours during periods when the instrument was being serviced (every 2-4 weeks). There are also occasional small gaps of several hours each when the pool was drained to service or switch out equipment from 2011 onward. Missing temperature values after May 2011 are entered as -100.

Data Processing Description

Where two HOBO Tidbit loggers were installed at the same time, the data are the average of the two readings.

BCO-DMO Processing

- Imported original file "Tatoosh Water Temp Cumulative BCO-DMO.csv" into the BCO-DMO system.
- Converted the date-time (local) field to ISO 8601 format.
- Added a date-time field in UTC in ISO 8601 format.
- Added columns for latitude and longitude and populated with the values provided in the metadata (all data taken from the same location).
- Renamed the "Average Temp, °C" column to comply with BCO-DMO naming conventions.
- Saved the final file as "916457_v1_tatoosh_island_surface_water_temp.csv".
