To access drifter data, there are custom links at nefsc.noaa.gov/drifter/. Click on your institution name to access the data (.csv) and the link in the status column to access the map (.html). If there is more than one track in the file, you can search by Deployment ID, which will be emailed to you.
Twice a year drifter data are reviewed and cleaned. This reviewed data (known as Quality Assured/Quality Controlled data, QA/QC) is available through ERDDAP. ERDDAP (previously an acronym, now just the name) is a data server that gives you a simple, consistent way to download subsets of scientific datasets in common file formats and make graphs and maps.
