What’s New for March 2009

1) Sea Ice Coverages now available in S-57 format

The Canadian Ice Service (CIS) has been working to develop sea ice Marine Information Overlays (MIOs) for use as supplemental information to ECDIS/ECS (Electronic Chart Display & Information System) systems.

In partnership with the Canadian Coast Guard (CCG), the CIS intends to test the production of S-57 ice MIO products this winter for use in the St. Lawrence and Gulf, and in Newfoundland waters. CCG and CIS are hoping to work with leading manufacturers and suppliers of Electronic Navigation Chart systems to test this new experimental ice MIOs.

If you are interested in participating in this test bed by enabling your systems to support these MIO products for your clients, please contact us.

What’s New for February 2009

1) New Ice Hazard Charts for Newfoundland and the Gulf of St. Lawrence

Starting this winter season, the Canadian Ice Service is introducing ice hazard charts for Newfoundland and the Gulf of St. Lawrence.

The Ice Hazard Chart is a graphical depiction of the Ice Hazard Forecast. It shows a generalized sea ice edge and iceberg limit as well as specific ice hazards. Any ice can be hazardous, but the Ice Hazard Chart indicates areas where there are additional dangers due to the ice motion, such as rapid closing of leads and strong ice pressure. Locations where sea ice would not normally be present because of the time of year or the geographic location are also noted. The legend gives more information about the features on the chart. During the winter season, this chart is issued each morning for the Gulf of St Lawrence and the Newfoundland areas.

2) Changes to the WIS27 North East Newfoundland Waters Chart

Starting this winter season, the Canadian Ice Service will use three charts to cover Newfoundland ice conditions. The charts will be as follows:

WIS27   North East Newfoundland (example)
WIS27E  East Newfoundland Waters (example)
WIS27NC Newfoundland Coast (example)

All three of the above charts are part of the Daily Ice Analysis Chart series.

They will also be available in colour under the Daily Ice Analysis Chart - Concentration and Daily Ice Analysis Chart - Stage series, with IDs as follows:

On any given day, all three, two, or just one of the charts may be updated, depending on the ice situation.
