We want to create a live underwater video stream, suitable for machine learning, and we want to add temperature and more parameters. We want our observatory to be ultralow cost and to require as little attention as possible.

Story
3 April 2024. Swedish public service television SVT features Fisktv on the evening news Rapport. An accompanying post is published on svt.se.
5 April. Local public service radio P4 Göteborg follows up with a short post.
19 September 2023. Recovering housing of observatory version 0.2 after first test at 30 m depth. Version 0.1 was without lid/endcap (!) and lasted just two hours.
13 December 2023. The improved Seapickle3 is deployed, with both salinity and temperature sensors, the later visible hanging below the jar.
19 December 2023. The jar experienced leakage within a few days. On the 19th it is retrieved and replaced with a Seapickle3 with identical interior and sensors, but with improved sealing.
The deployment is changed from hanging to bottom moored. The reason is the risk of ice on the line and hence weight on the suspension bridge.
