Abstract:

Marine heatwaves are modelled off their terrestrial namesakes and are prolonged periods of anomalously high sea surface temperature (SST). In effect, they are categorized SST anomalies. They are also a more general version of the Coral Reef Watch (CRW) daily global 5km coral bleaching "HotSpot" product. Rather than being aimed specifically at corals, however, they provide a more generalized description of marine heat stress that is likely applicable to a broader range of marine life. This daily global 5km-resolution Marine Heatwave Watch (MHW) product is derived by applying the marine heatwave algorithm of Hobday et al. (2018) to the daily global 5km "CoralTemp" SST data product. CoralTemp is one of the best and most internally consistent daily global 5km SST products available, which allowed for the creation of an accurate climatology. This enabled the derivation of an accurate, consistent MHW product (comprised of near real-time and historic components), stretching back over three decades. Provides the most recent 3 years of data only; for the full time series, see PacIOOS ERDDAP instead.

Purpose:

PacIOOS provides timely, reliable, and accurate ocean information to support a safe, clean, productive ocean and resilient coastal zone in the U.S. Pacific Islands region.

Statement:

2021-09-22T12:00:00Z Initial version released: v1.0.
2021-09-22T12:00:00Z Version 1.0.1 released. Fixed minor compatibility issue loading data into GIS applications by altering dimension names and coordinate variable names.
2023-01-05T19:26:00Z Data obtained from NOAA Coral Reef Watch and re-distributed via THREDDS Data Server (TDS) at PacIOOS to provide temporal aggregation and distribution through NetCDF/OPeNDAP utilities like ncWMS and ERDDAP.
2024-01-12T22:35:00Z Due to ongoing difficulty serving the entire time series aggregation through TDS, we are now limiting access to the latest 3 years. For the full time series, see PacIOOS ERDDAP instead.
2024-03-20T21:18:00Z Full time series aggregation now restored in TDS; no longer limited to latest data.
2024-04-04T07:21:00Z Due to ongoing difficulty serving the entire time series aggregation through TDS, we are now limiting access to the latest 3 years. For the full time series, see PacIOOS ERDDAP instead.
2024-07-18T19:00:00Z Due to changes in data format from CRW, time series aggregation is no longer possible with files before July 1, 2024.

Descriptor:

marine heatwave category. This variable provides a measurement of daily sea surface temperature anomaly (SST Anomaly) based on an intensity classification algorithm for tracking marine heatwaves. Its value determines the contribution of the daily SST anomlay to the occurrence of a marine heatwave event and/or duration and intensity of an ongoing event. The value range is: 0 - No contribution to a marine heatwave event; 1 - Category I (Moderate); 2 - Category II (Strong); 3 - Category III (Severe); 4 - Category IV (Extreme); 5 - Category V (open-end beyond Extreme).
