  • The dataset comprises hourly water temperature data of an experimental mesocosm facility as well as air temperatures from beginning of July to end of September 2022. The experiment aimed to investigate the effect of different nutrient regimes on Taste and Odour issues. Mesocosms were filled with reservoir water and water temperature was measured by platinum resistance thermometers (PRT) shaded by a plastic cover, sited around mid-depth, radially offset by 30 cm from the mesocosm's side wall and logged by a Campbell Scientific Data Logger. Air temperature was measured at a weather station within the mesocosm compound (Vaisala weather transmitter WXT520) at around 2.7m height.

  • This dataset consists of high resolution tiff photographed images of tide gauge charts, from various historical tide gauges from the Grand Harbour (Port of Valletta), Malta. Due to the historical nature of these records, there is little associated metadata with the original charts. They come from various individual tide gauge locations around the Grand Harbour (Port of Valletta), Malta, and some are labelled with more specific locations, such as French Creek and Ricasoli Breakwater. General coordinates have been given for the geographic coverage: 14.49E to 14.53E, 35.87N to 35.9N. The earliest chart is from the 01/06/1871 and the latest is from 1926. There are gaps of several years in the dataset. In his 1878 paper, On the tides at Malta, G. B. Airy describes the gauge in operation in 1871: "The float was a copper vessel, nearly spherical, about 8 inches in diameter; a vertical rod attached to it passed freely through a guide, and was hinged to the end of a horizontal lever, of which the arms were so proportioned that each space marked on the tabular form between the horizontal lines [one-fourth of an inch. - G.B.A.] corresponded accurately to an inch rise or fall of the float." "The cylinder on which the paper was wrapped revolved once in 24 hours". It is not known how long this gauge was in operation for, but all of the tide gauges that produced the tide gauge charts in this dataset would have been float gauges. The original charts were collected by the Royal Navy as part of their surveying duties of the Grand Harbour. The United Kingdom Hydrographic Office (UKHO) had these charts in its archives, which were difficult to access and in need of conservation. The charts were conserved and photographed and made publically available as digital images to help preserve one of the longest and earliest temporal series of sea level data in the Mediterranean. The original data were collected by the Royal Navy and were placed in the archives of the Admiralty, now the UKHO. The conserved and photographed images were created by the United Kingdom Hydrographic Office Archives for the MALTESER, MediterrAnean Long TErm SEa level Rescue project and then deposited with the British Oceanographic Data Centre. This project was funded under the Central Government Breakthrough Fund, 2014. Reference: Airy, G. B. (1878). On the tides at Malta.

  • This Met/Ocean data bank comprises wave, current, water temperature and surface meteorology (air temperature, humidity and wind) data collected at 11 off-shore sites on the UK continental shelf, between 1973 and 1988. Three hourly wave data (short term statistics) and hourly wind observations together with atmospheric pressure, air temperature and, occasionally, sea surface temperature were measured at weather ships (W.S.) Stevenson (61 20.0N, 000 00.0E from 1973 - 1976), Fitzroy (60 00.0N, 004 00.0W from 1973 - 1976) and Boyle (50 40.0N, 007 30.0W from 1974 - 1977). Moored current meter measurements were also made at 2 to 4 depths at each site. Three-hourly measurements of sea temperature, air temperature, barometric pressure, relative humidity, wind speed and wind direction were collected at the National Data Buoy DB/1 site (48 43.0N, 008 58.0W) between 1978 and 1982. Directional spectra of the wave field were also derived from measurements of heave, pitch and roll of the buoy, while surface currents were measured hourly. DB/1 was succeeded by DB/2 (located at 48 44.0N, 008 50.0W from 1984 - 1986 and at 58 59.0N, 007 13.0W from 1986 - 1988) and DB/3 (60 30.9N, 002 52.0W from 1984 - 1988). Met/Ocean data and directional wave spectra are available from these sites, comprising hourly recordings of wind speed and direction, maximum wind gust speed, air temperature, relative humidity, barometric pressure (and pressure trend over three hours), sea temperature, significant wave height and period, maximum wave height, swell wave height, period and direction, wind wave height and period, current speed and direction. The directional wave spectra consist of the 9 co- and quad- spectral densities for 51 frequency slots, plus derived height, period, direction and directional spread of all waves, wind waves, swell waves and spectral peak wave period. The UKOOA dataset also includes measurements from four platforms, with short term wave statistics, hourly wind observations, atmospheric pressure, air temperature and occasionally sea surface temperature data available from Forties (57 45.0N, 001 00.0E) between 1974 and 1980; Brent (61 04.0N, 001 43.0E) between 1975 and 1980; and Beryl/Frigg (59 35.0N, 001 40.0E) between 1979 and 1982. One dimensional wave spectra and meteorological data are available from Foula (60 08.0N, 002 59.0W) between 1977 and 1979. All data were collected by the UK Offshore Operators Association (UKOOA) and are stored at the British Oceanographic Data Centre (BODC).

  • This datasets contains a box model of the atmosphere‐ocean to understand surface warming response and explain how surface warming varies in time with carbon emissions. The box model consists of three homogeneous layers: a well‐mixed atmosphere, an ocean mixed layer with 100‐m thickness, and an ocean interior with 3,900‐m thickness, all assumed to have the same horizontal area. The model solves for the heat and carbon exchange between these layers, including physical and chemical transfers, but ignoring biological transfers, and sediment and weathering interactions. The model is forced from an equilibrium by carbon emitted into the atmosphere with a constant rate of 20 PgC/year for 100 years and integrated for 1,000 years. Ocean ventilation is represented by the ocean interior taking up the heat and carbon properties of the mixed layer on an e-folding time scale of 200 years. The model was generated as part of Natural Environment Research Council (NERC) Discovery Science project “Mechanistic controls of surface warming by ocean heat and carbon uptake” standard grant reference NE/N009789/1 lead by Principal Investigator Professor Ric Williams.Model code and associated metadata are held in the archives at the British Oceanographic Data Centre. Other datasets generated by this grant are discoverable via EDMED 6712.

  • The Joint North Sea Data Acquisition Project (JONSDAP) dataset comprises hydrographic and meteorological time series, including current velocities, water temperature (both at the sea surface and at depth), hydrographic pressure, air temperature, barometric pressure and wind velocities. The data were collected in the North Sea from March-June 1976. Automatically recording current meters (and usually temperature sensors), off-shore tide gauges, thermistor chains and meteorological data buoys were deployed at numerous locations around the study area for periods of a few days to several weeks. Data from 9 tide gauge, 4 meteorological data buoy, 10 thermistor chain and 81 current meter deployments are held at the British Oceanographic Data Centre (BODC). Additional hydrographic data were collected during JONSDAP 76 cruises, while over-flights with aircraft provided further measurements. However, these data are not stored at BODC. JONSDAP 76 consisted of two parts: FLEX, the Fladen Ground Experiment between 25 March and 15 June, and INOUT, the inflows of water of the whole North Sea as well as the internal movements from 15 March to 25 April. The data were collected by 13 laboratories in 8 countries.

  • Within Pacific Small Island Developing States (Pacific SIDS), the ridge-to-reef (R2R) approach has emerged as a framework for monitoring river connectivity between terrestrial and marine ecosystems. The study measured water quality, including pH and a range of othe physical and chemical properties over 88.40 km of the Ba River in Fiji. The sampling design focused on measuring spatio-temporal variability in pH throughout the sugarcane season (April - August) with three rapid sampling periods (RSP1, 2 & 3) along the Ba River, together with continuous measurement of temperature and pH using stationary data loggers at two locations upstream and downstream of the sugar mill (April to August 2019). Spatial variability in pH and water quality was characterized before (RSP1 and RSP2) and during (RSP3) the sugarcane season. Mean pH measured before the sugarcane crushing season for RSP1 and RSP2 were 8.16 (± 0.49) and 8.20 (± 0.61) respectively. During the sugarcane crushing season (RSP3) mean pH declined by 3.06 units to 6.94 within 42 m downstream of the sugar mill (P < 0.001). The 3.06 unit decline in pH for RSP3 exceeded both the mean diurnal variation in pH of 0.39 and mean seasonal variation in pH of 2.01. This decline in pH could be a potential source of acidification to downstream coastal ecosystems with implications for coral reefs, biodiversity and fishery livelihoods.
