ACOLITE-processed Sentinel-2 MSI ocean colour products for seagrass carbon stock modelling
Abstract
This dataset contains water quality products derived from Sentinel-2 MSI over seagrass sites in northern temperate coastal regions. For each seagrass site, a 20 × 20 km area was extracted, and all available Sentinel-2 observations from June 2015 to June 2022 were processed. The subsets of the scenes are provided as individual NetCDFs. The dataset includes the following variables: Chlorophyll a concentration (OC3 and red edge algorithm, Gons et al. 2002), Turbidity (Nechad et al. 2009), Suspended matter concentration (Nechad et al. 2010 ) and Secchi depth (ACOLITE QAA-pq3aa). These variables were used as inputs for machine-learning models described in Wilson et al. (2025, doi: https://doi.org/10.3389/fmars.2025.1714518). Due to high intercorrelation, only turbidity was retained in the final model.

Level 1C Sentinel-2 scenes were downloaded from the Google Earth Engine Catalogue collection. Atmospheric correction was undertaken with ACOLITE using default settings. Processing was undertaken on MAGEO (Massive GPU cluster for Earth Observation) by the NERC Earth Observation Data Analysis and AI Service (NEODAAS) and supplied for archiving at the Centre for Environmental Data Analysis (CEDA). Note the data provided are not full Sentinel-2 scenes, but subsets extracted around the study sites. These subsets typically cover a 20 × 20 km box centered on each sample location. Where multiple sites fall within the same Sentinel-2 tile, the subset area was expanded to include all site locations within that tile. |
