I was going to write maybe they just get the data from bottles that make it close to shore and to a cell antenna, and if a significant percentage don't call back, then they could assume the currents take them out to sea.
But the diagram of the bottle credits "ARRIBADA INITIATIVE", and https://arribada.org https://arribada.org says:

Geez, I thought sat com would need big hardware, but it seems they've got it on a tiny board: https://www.cls-telemetry.com/argos-solutions/argos-products/modems/artic-chipset/#Open-Source-Reference-Design https://www.cls-telemetry.com/argos-solutions/argos-products...
