Sea temperature with warm-core and cold-core eddies in the Tasman Sea

Temperature and eddies

Sea temperature, breaks and eddies

Gannet View draws sea surface temperature at 1 km where the satellites have a clear look, and measures the break for you: how sharp it is, how far away, and which way the warm water lies. Over it, sea level from satellite altimetry marks the warm-core and cold-core eddies that persist for weeks, with their strength written on them.

  • Colour range you can tighten to the degree that matters today
  • Temperature break distance and slope on every tap
  • High and low tags on every eddy, contours in your units
  • Past passes, and a forecast that fades honestly toward the model

How it works

Sea surface temperature is drawn at about 1 km wherever a satellite has had a clear look, with the date of the pass shown on the layer. You can tighten the colour range to the single degree that matters on the day.

A temperature break is where one body of water meets another. Tap the map and Gannet View measures the nearest break for you: how sharp it is, how far away it lies and which way the warm water sits.

Eddies are picked out of satellite sea level (altimetry). A warm-core eddy is a high, a cold-core eddy is a low, and each is tagged so you can see which is which and how strong it is.
