String abstract
"This dataset contains time series observations of chlorophyll-a fluorescence recorded with an ECO WetLabs fluorometer (S/N 1514) deployed on a seabed mounted instrument frame at site M4 (57.018289N, -1.838832E) in the northern North Sea near the Kincardine Floating Offshore Wind Farm.
The dataset spans 14 August 2025 to 3 September 2025 and was collected during the DY197 research expedition (RRS Discovery), during which the instrument was deployed and recovered.
These observations were collected as part of the NERC and Crown Estate funded ECOFlow programme, EQUIFy, Establishing a Framework for Quantifiable Evidence and Impact of Ecosystem Change Throughout the Lifecycle of UK Floating Offshore Wind Farms, grant number NE/Z504099/1. EQUIFy aims to co deliver a transferable monitoring and evidence framework that quantifies ecological impacts from future floating offshore wind development across spatial and temporal scales.";
String acknowledgement "EQUIFy is part of the NERC and Crown Estate funded ECOFlow programme, grant number NE/Z504099/1. The authors wish to thank the officers and crew of RRS Discovery, the NMF staff and the eSWEETS3 project for their assistance in collecting these data.";
String analytical_protocol
"Raw ECO WetLabs fluorometer data were read from engineering units and converted to chlorophyll-a concentration using the manufacturer supplied scale factor and dark count from the calibration sheet.
Initial quality control included despiking of the chlorophyll-a time series using a moving window approach (3 standard deviation threshold), applied over approximately half a tidal cycle based on the sampling interval.
The resulting chlorophyll data were calibrated against CTD observations from casts CTD014 and CTD200.";

"An ECO WetLabs fluorometer (S/N 1514) was deployed on a stable seabed mounted instrument frame at site M4 (57.018289° N, â^'1.838832°E) in the northern North Sea near the Kincardine Floating Offshore Wind Farm. The instrument was deployed and recovered during the DY197 research expedition (RRS Discovery).
The fluorometer recorded a time series of chlorophyll-a fluorescence near the seabed as a proxy for phytoplankton biomass. Measurements were collected at a sampling interval of 11 minutes throughout the deployment period.
The dataset spans the full observation period from 14 August 2025 to 3 September 2025.";

Data Access Protocol (DAP) and its
selection constraints.
The URL specifies what you want: the dataset, a description of the graph or the subset of the data, and the file type for the response.
Tabledap request URLs must be in the form
https://coastwatch.pfeg.noaa.gov/erddap/tabledap/datasetID.fileType{?query}
For example,
https://coastwatch.pfeg.noaa.gov/erddap/tabledap/pmelTaoDySst.htmlTable?longitude,latitude,time,station,wmo_platform_code,T_25&time>=2015-05-23T12:00:00Z&time<=2015-05-31T12:00:00Z
Thus, the query is often a comma-separated list of desired variable names,
followed by a collection of
constraints (e.g., variable<value),
each preceded by '&' (which is interpreted as "AND").
For details, see the tabledap Documentation.
