Sea Ice – October 2009

Continuing from

Spline Smoothing

The 2009 Climate Dynamics paper “Unprecedented low twentieth century winter sea ice extent in the Western Nordic Seas since A.D. 1200” by M. Macias Fauria, A. Grinsted, et al. discussed already on the thread Svalbard’s Lost Decades pre-smooths its data with a 5-year cubic spline before running its regressions. There’s been a lot of discussion […]

Sea Ice – August 2009

Continuation from [insert]. The graphic below shows the daily change in sea ice extent (JAXA). The end of the melt season is about day 259 (about 40 days from now.) The big 2007 was early in July. 2008 had a prolonged melt through August. In the last week or so, 2009 slowed down pretty dramatically. […]

Sea Ice At Lowest Level In 800 Years

A few days ago, Jeff Id drew attention to a recent study profiled in sciencedaily which stated: Sea Ice At Lowest Level In 800 Years Near Greenland ScienceDaily (July 2, 2009) — New research, which reconstructs the extent of ice in the sea between Greenland and Svalbard from the 13th century to the present indicates […]

Sea Ice – June 2009

June 2009 monthly sea ice data is now out for NH and SH. (Continuing prior sea ice post here.) The global sea ice anomaly in June 2009 remained positive. Over the 1979-2009 period, there is zero trend in global sea ice anomaly, with a SH increasing trend offsetting a NH decreasing trend. June 2009 NH […]

A New Sea Ice Thread

Prior post here. Next post here Sea ice threads always seem to be popular. For people interested in handling data themselves, I’ve updated my utility functions for reading sea ice data here. It contains methods for accessing JAXA, monthly NOAA and NSIDC binary. (The latter works but I haven’t verified the turnkey version. Jeff Id […]

Sea Ice Satellite Failure

In case you’ve missed it, WUWT has an excellent post on failure of a sea ice satellite sensor – now taken offline.

Antarctic Sea Ice Re-visited

Jeff Id did an interesting post a few days ago on Antarctic sea ice in which he provided the following interesting graphic of Antarctic seaice area anomalies, which, from the texture, is daily, rather than monthly: Figure 1. Antarctic seaice area anomaly (Jeff Id version) Jeff’s data reference was to the following webpage at NSIDC, […]

Sea Ice 2009

For sea ice devotees.

Ward Hunt Ice Shelf Stratigraphy

The Ward Hunt Ice Shelf has a rather complicated history and stratigraphy. Fortunately, the original studies of the Ward Hunt Ice Shelf in the 1960s and 1970s were done by geologists rather than climatologists and, as a result, there are decent maps in the early literature showing relevant details of the stratigraphy. (Compare their maps […]
