sea ice
Let an agent explain sea ice and its formation, types and dynamics, describe its role in climate and ecosystems, relay observational data and trends from scientific bodies, and support navigation, cultural and policy questions with attribution.
Research draft, second pass
A second pass drafted this model: the structure a model of this thing needs, and what is known about it in the world. The line under this one says how the second half was obtained - researched against sources, or recalled without web access, in which case nothing here was read anywhere and every claim is a lead to verify. Unreviewed either way.

Purpose and description
Let an agent explain sea ice and its formation, types and dynamics, describe its role in climate and ecosystems, relay observational data and trends from scientific bodies, and support navigation, cultural and policy questions with attribution.
Frozen seawater that forms, grows and melts in the ocean, from new grease ice through pancake and first-year ice to multi-year ice, occurring as drifting pack ice and as fast ice attached to shores, covering large areas of the Arctic and Southern Oceans with strong seasonal cycles; sea ice regulates climate by reflecting sunlight and insulating the ocean, is habitat for polar species, is central to Inuit and other Arctic peoples, and is declining in the Arctic according to long-term observations.
What it is for: Frozen seawater in the ocean.
It can be explain formation and types; describe climate and ecosystem roles; relay data and trends; support navigation and policy questions.
Distinguishing features
Salt water origin
Seasonal cycle
Pack and fast ice
Climate feedback
What it looks like
Floating ice sheets and floes on the sea.
How it is recognised
Ice formed from seawater
Grease ice, pancake ice, first-year, multi-year, fast ice
Icebergs are freshwater ice from glaciers; ice shelves are floating glacier extensions
