pH trends project

Youngling Posts: 3 Join Date: 6/12/17 Recent Posts

As I was not able to find modeled ocean carbonate datasets from satellites through CoastWatch or ERDDAP, I searched other sites to find the data. I selected NOAA's ocean acidification product suite developed by the Acidification, Climate, and Coral Reef Ecosystems Team Lab of AOML’s Ocean Chemistry and Ecosystems Division. While experimental, this dataset is created by a trusted source and covered the temporal and regional scale of the project at an appropriate resolution.

Marissa,  you may want to see if these data are userful:  https://cwcgom.aoml.noaa.gov/erddap/griddap/miamiacidification.graph

Thanks! The temporal resolution is even better in this dataset, but it doesn't cover the region I need. If you have any other data links, please send them along!

Unfortunately I don't have additional links.  From our Atlantic OceanWatch node at AOML,  they advise "The model works for this oligotrophic area but not in the GoM. We are working on having a global model but results are not still available."

Hi Marissa, Unfortunately, pH from space is still very much a work in progress. There are models out there, but they need to be tuned regionally, so it's highly dependent on how much in-situ data is available in each region. I was actually working on a pilot project for the central Pacific, but we haven't published the data because we have no way to validate the results until we are able to collect more in situ data.  So for the carbonate system, you might be better off using model data until these products become more mature.

And I misspoke, there aren't model data available that I know of....
