The State of the Global Climate report for 2023 is now out (wmo.int) which shows that the global ocean experienced an average daily MHW coverage of 32%, well above the previous record of 23% recorded in 2016.

Diving into a crucial issue – marine heatwaves. These prolonged ocean warming events wreak havoc on our marine life, decimating kelp forests & seagrass meadows. Noticed any unusual changes in our waters? Share your stories. #greatsouthernreef #marineheatwaves #giantkelp

Sea temps across much of the global ocean are alarmingly high, with extensive MHW activity. However, coastal waters off Japan have been in a near-permanent MHW state for ~1 year. The current winter MHW is remarkable, with max intensity of >11 degC !!! #marineheatwaves #MHWs

New paper examines drivers of marine heatwaves in the Arctic, which have intensified in recent decades:

The MHW in the western Indian Ocean, off Madagascar, continues to develop, with absolute temps exceeding 28 degC (~3 deg C warming anomaly)

After a brief respite in October, the long-term MHW off northeast Japan has re-established with unseasonably warm waters. Could have major implications for coastal habitats eg kelp forests.

An astonishing 45% of global oceans are experiencing a marine heatwave right now (90th percentile of sea sfc temp in a given area). What is the normal extent of marine heatwaves around the globe? Just 10% coverage. It's been stunning summer. More on MHW marineheatwaves.org/all-about-mhws…

New study exposes alarming vulnerabilities of the Tasmanian #kelp , Lessonia corrugata, as it faces unprecedented challenges due to rising ocean temperatures. Researchers identify a critical maximum limit of 22-23°C.

#DataVisualization

As sea temperatures increase, it is vital to track the extent and the frequency at which marine heatwaves (MHW) occur.

➡️ This map shows all global marine heatwaves for 2021 and 2022.

Are you planning to go to #EGU24 in Vienna, Austria and are working on #MarineHeatwaves ? See the session below, which I am co-convening - please share widely.
Abstract submission deadline is January 10th 2024 13:00 CET (7am ET).

The forecasted marine heatwave off south-east Australia has emerged and strengthened into December. A series of national briefings led by CSIRO and Bo Myraas have helped a range of marine stakeholders to prepare for this summer heatwave

Species respond to MHWs in different ways. Building on the basic MHW metrics, a new study develops a hazard index for fisheries and aquaculture - one step towards a marine heatwave risk index.
