Data — Samples, Sources, Permissions

WII5 data — sample buoy output, links to public WII datasets on Mendeley, and the permissions / ownership rules around what we can publish.

Figure 3 from Kohout *et al.* (2014), [*Storm-induced sea-ice breakup and the implications for ice extent*](publications/), **Nature** 509. WII buoy data showing the relationship between wave height and ice-edge retreat.

Real buoy data, where we can publish it.

  • Sample data — small examples of decoded buoy output (CSV / JSON), an Iridium SBD payload schema, and reference plots.
  • Public archives — historical WII deployment datasets published by Dr Alison Kohout (NIWA) on Mendeley. Mirrored as pointer pages below.
  • Permissions and ownership — who owns the data from each deployment and what’s open vs restricted. Not every deployment can be published.

Public deployment datasets

These are the publicly released WII observation datasets from Alison Kohout’s project page. Each links to the canonical Mendeley archive.

  • SIPEX II — East Antarctic sea ice, 2012. Five WIIOS units, 268 wave records.
  • PIPERS — Ross Sea, 2017. Fourteen WIIOS units, 23,000+ wave records during autumn ice growth.
  • JARE61 — East Antarctica, 2019/20 summer. Additional WIIOS units with notably longer survival times on seasonal ice.

Publications

  • Publications — the peer-reviewed papers produced from these datasets, including the 2014 Nature paper on storm-induced sea-ice breakup. Mirrors Alison Kohout’s bibliography.

The WIIOS sensor (Waves in Ice Observation System) is the Alison-Kohout-designed instrument behind these datasets. WII5 is the current generation of buoy built on the same lineage. See Software → Onboard Data Processing for how the on-board maths reduces the data shown in those datasets.
