Hi, @CharlesAnderson I know this reply is coming to you a little late! But whenever I want general CSV data for SST (sea surface temperature) anomalies, climate, or temperature I go to this website NOAA Climate.gov because they have a lot of open downloadable data and interactive maps.
Here is the general website:
https://www.climate.gov/maps-data/datasets?page=1
Here are the Global Temperature Anomalies CSV data that is awesome and I use often:
https://www.climate.gov/maps-data/dataset/global-temperature-anomalies-graphing-tool
Here is the data page for temperature and precipitation trends:
https://www.climate.gov/maps-data/dataset/temperature-and-precipitation-trends-graphing-tool
Here is the page for Sea Surface Temperature:
https://www.climate.gov/maps-data/dataset/sea-surface-temperature-and-sea-ice-coverage-map-viewer
I have not used these USGS geomagnetism CSV data sets (they're not specific to the poles) but you can find the general page here: Scroll and click on the data sets at the bottom of the page.

and here is one that I think might be helpful from the USGS Geomagnetic Repeat Station:

Hope this helps!
Best,
