Figure 1) Current SST, SSTA Conditions and Shipping Route Information.


The tabs below show the daily 5km SST and SST anomalies (SSTA) for 2025-02-01.

Current conditions are based on the latest remotely sensed data from NOAA Coral Reef Watch and GHRSST L4. For comparison, the SSTA conditions are also shown for exactly 1 year prior (2024-02-01).

The light green lines and ship icon represent the 2024 route and turtle release location on July 7, 2024.
The in situ SST measurement on that date was: 18°C.

For comparison, the dark green lines and solid icon represent the 2023 route and turtle release location on July 10, 2023.
The in situ SST measurement on that date was: 24.8°C.

The 4 circles represent longitudes of interest across the eastern North Pacific Ocean. Figure 2 shows a time series of SST conditions at these 4 longitudes. Black lines represent the 18°C isotherm. The Thermal Corridor area is outlined in white.

Current SST Conditions: 2024


Current SST Anomalies: 2024


Previous Year’s SST Anomalies: 2023



Figure 2) Average SST time series.

Weekly and long-term average sea surface temperatures at 4 longitudes in the eastern North Pacific:

* 43°N 160°W

* 41°N 150°W

* 40°N 145°W

* 38°N 140°W

For each longitude, the darker lines with circles represent the weekly SST average since 2023.

To compare the current SST values (2023-present) with the long-term average for the same time period, the lighter solid lines represent the long-term monthly SST averages between 1997-2022.

The black horizontal line at 18°C was used as a reference for optimal temperatures during turtle release.
