      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.

      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.

        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.

        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,

            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).

            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.
