An Ocean-Colour Time Series for Use in Climate Studies: The Experience of the Ocean-Colour Climate Change Initiative (OC-CCI) [PDF]

Sensors, 2019
Ocean colour is recognised as an Essential Climate Variable (ECV) by the Global Climate Observing System (GCOS); and spectrally-resolved water-leaving radiances (or remote-sensing reflectances) in the visible domain, and chlorophyll-a concentration are ...

Global Drivers of Phytoplankton Phenology Trends. [PDF]

Glob Chang Biol
Observations and a global biogeochemical model were used to examine recent shifts in phytoplankton phenology at the global scale. Sea surface temperature trends emerge as the strongest predictor of these changes, relative to the other drivers considered, and are associated with earlier initiation, later termination, and longer growing periods ...

Satellite data is revealing long time changes in the world largest lakes [PDF]

Scientific Reports
Lakes are a crucial source of drinking water, provide ecological services from fisheries and aquaculture to tourism and are also a critical part of the global carbon cycle. Therefore, it is important to understand how lakes are changing over time.

A new global oceanic multi-model net primary productivity data product [PDF]

Earth System Science Data, 2023
Net primary production of the oceans contributes approximately half of the total global net primary production, and long-term observational records are required to assess any climate-driven changes. The Ocean Colour Climate Change Initiative (OC-CCI) has

A nationwide assessment of hepatocellular adenoma resection: Indications and pathological discordance

Hepatology Communications, EarlyView., 2022
Abstract Hepatocellular adenomas (HCAs) are benign liver tumors associated with bleeding or malignant transformation. Data on the indication for surgery are scarce. We analyzed indications and outcome of patients operated for HCAs < 50 mm compared to HCAs ≥ 50 mm. Changes in final postoperative diagnosis were assessed.

Sea Surface Chlorophyll-a Concentration Retrieval from HY-1C Satellite Data Based on Residual Network

Remote Sensing, 2023
A residual network (ResNet) model was proposed for estimating Chl-a concentrations in global oceans from the remote sensing reflectance (Rrs) observed by the Chinese ocean color and temperature scanner (COCTS) onboard the HY-1C satellite.
