Data disappeared from ArcGIS Online

gemmascottScott — Tue, 02 Dec 2025 15:40:19 GMT

Two data layers that were in arcgis online are missing:

Global Sea Surface Temperature - Monthly Mean (1982-2022)

and:

“Chlorophyll-a monthly mean climatology” tiled imagery layer by Esri_Ocean in ARCGIS

Anyone know where they've gone?

Any suggestions for alternatives?

Thanks!

Hey @gemmascottScott

I'm seeing that the Chlorophyll is now giving a permission error and I can't seem to locate the Global Sea Surface Temperature maps. I did find potential KML alternatives for the temperature here: https://www.climate.gov/data/Ocean--Monthly--Difference-from-average-Sea-Surface-Temperature--Global/05-kml/

And then the Chlorophyll there's an alternative here (potentially): https://www.arcgis.com/home/item.html?id=ba1c287a56b342319753cee029e2dbfc

Since these are both Esri maps, it is definitely possible that the maintainer or creator of these maps will see your post and be able to give you an answer, you could definitely call in to see if they could give you a reason as well! Hopefully they get them back up!

Hi @gemmascottScott,

Have you tried searching for them in ArcGIS Online?

@EmilyGeo They were missing until this morning 🙂

Got the word from the esri team mid-day that they had been accidentally unshared after some data clean up, but they got them turned back on! Thank you to all!
