attribute NC_GLOBAL abstract String 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.\nThe 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.\nThese 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.
attribute NC_GLOBAL acknowledgement String 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.
attribute NC_GLOBAL analytical_protocol String 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.\nInitial 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.\nThe resulting chlorophyll data were calibrated against CTD observations from casts CTD014 and CTD200.

attribute NC_GLOBAL sampling_protocol String 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).\nThe 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.\nThe dataset spans the full observation period from 14 August 2025 to 3 September 2025.
