The map now centers on the farm itself, and the water forecast and satellite views from the last release are on the site. Live site: https://robertslab.github.io/acantha/

On the map

  • Farm layout. The bag blocks and the research-bags line, drawn from the farm schematic, with a popup per block. The map now opens zoomed to the farm (web/farm-layout.geojson; edit it in geojson.io).
  • Tide height lines. Contours every 2 ft from −6 to +12 ft MLLW around the farm, the same datum as the tide predictions, so a −2 ft low uncovers everything above the −2 ft line. Built from NOAA's 1/9 arc-second Puget Sound DEM by baseline/tide_contours.py, with NAVD88 shifted to MLLW using the Whitney Point (9445246) datums.
  • Farm photos. Geotagged photos dropped into photos/ become clickable markers with the picture, caption and date. photos/build.py publishes metadata-free web copies only; originals stay out of the repo. JPEG, HEIC and PNG work. See photos/README.md.
  • Satellite view (Sentinel-2). A scene picker with capture time, clear % at the bay and tide at capture, plus a Satellite card linking to the last clear view.
  • LiveOcean model cells drawn as hollow markers with a forecast chart.

On the dashboard

  • Water forecast card. UW LiveOcean surface temperature and salinity: now, the 3-day range, a 10-day chart with Port Townsend observations overlaid, and the recent model-vs-observation bias.
  • Flags use the model. The Vibrio check falls back to the model surface temperature when no observation is current and warns when the forecast reaches the threshold. A drop in salinity at the bay mouth adds a runoff note. Both thresholds are user settings.

Farm sensors

  • The Dragino D20-LB test unit now reports through The Things Network.
  • Every reading is archived to monthly CSVs on the sensor-data branch, so data is no longer lost after the site's 7-day window.
  • New guide for adding gateways and sensors: docs/sensors.md.
  • Clearer TTN errors, and paged storage requests so fetching doesn't hit TTN's limit.

Known gaps

  • The test sensor is listed at 8 ft (an estimate), but the elevation model puts that spot near 0 ft MLLW, so its in-water/exposed status may be off until the elevation is measured.
  • The farm layout is missing the lower-right block, buoys and edge lines from the schematic.
  • Still no live dissolved-oxygen or pH source for northern Hood Canal while the ORCA buoys are offline.
