Marine Heat Waves (MHW) consist of localised, persistent, and anomalously warm seawater temperature events usually detected at the sea surface level. Continuous monitoring of sea surface temperature, from both remote sensing observations and numerical models, is essential to detect such events and manage their impacts.
MHW are climate-induced phenomena affected not only by long term climate changes but also by short-lived extreme weather events. It is under this scope that MHW have been the topic of recent scientific advances and discussions aiming to better understand how they influence the ocean health.
deteCtion and threAts of maRinE Heat waves
CAREHeat (deteCtion and threAts of maRinE Heat waves) is a project funded by the European Space Agency (ESA) which is focused on extreme MHW. It aims to improve existing MHW detection algorithms, contributing to a better understanding of their impacts.
CAREHeat will therefore contribute to better understand the complex interaction between global climate change and local transient effects on sea surface temperatures that can pose significant ecological and economic impacts.
CAREHeat employs novel Earth Observation (EO) products for various purposes, including:
Development, implementation, and validation of an improved version of the current Hobday-based MHW detection workflow
Demonstration of the feasibility of blending EO remote sensing data, from Sentinel and Copernicus, with in-situ measurements and numerical model outputs, through machine learning techniques, to successfully reconstruct and provide insights into the spatio-temporal evolution of MHW events
Advance the current scientific knowledge on MHW occurrence, including disclosing the contribution of climate change and climatic modes to their prevalence, effects on ecosystems and biogeochemistry, and its role in more complex compound events
Establish the added value of the MHW EO novel products to society, by examining its performance in predicting corresponding biological and/or economic losses
