The Arctic Archipelago, also known as the Canadian Arctic Archipelago, groups together all islands lying to the north of the Canadian continental mainland excluding Greenland (an autonomous territory of Denmark).

Situated in the northern extremity of North America and covering about 1, km 2 (, sq mi), this group of 36, islands in the Arctic Sea comprises much of the territory Location: Northern Canada.

Planet earth is a giant magnet. Humans have used earth's magnetic fields as a way of navigating over great distances for hundreds of years.

But in the last century scientists have discovered that igneous rocks (from volcanic lava) record a very important piece of information about earth's magnetic field at the time they are formed - where geomagnetic north and south poles were located at the.

Variation in the density of stippling is used, in Fig.4, to attempt to show some- thing of the conductive fine structure. D.I. Gough, Geomagnetic variation anomalies files of Archambeau et a!.

The diurnal-variation anomalies of the vertical-component in geomagnetic field are mainly the changes of phase and amplitude before strong earthquakes.

Our knowledge of historical secular variation in the Arctic is only limited to the last years (Jackson et al. ; Jonkers et al. The Arctic geomagnetic field, as re-vealed by recent satellite data as well as ground-based meas-urements, is characterized by secular variation at a muchFile Size: 3MB.

Now that we know the rock ages, we can look at the Earth’s magnetic field during this time window. The South Atlantic Anomaly (SAA, the large red area in the image) is a dip in the Earth's magnetic field which allows cosmic rays, and charged particles to reach lower into the atmosphere.

This interferes with communication with satellites. Knowledge of past variations in the intensity of the Earth's magnetic field provides an important constraint on models of the geodynamo.

This double map is the result of a close international cooperation gathering research organisations of Russia, Canada, USA, Finland, Sweden. Cores from Northwind Ridge, a high-standing continental fragment in the Chukchi borderland of the oceanic Amerasia basin, Arctic Ocean, contain representatives of every Phanerozoic system except the Silurian and Devonian systems.

Cambrian and Ordovician shallow-water marine carbonates in Northwind Ridge are similar to basement rocks beneath the Sverdrup basin of the Canadian Arctic Archipelago. The GUFM model (Jackson et al.,Four centuries of geomagnetic secular variation from historical records, Phil.

The Canadian Arctic Archipelago (CAA) is home to one of the world's largest glaciated areas (∼, km 2), comprising ∼14% of Earth's total ice‐covered area outside the ice sheets of Greenland and Antarctica (Sharp et al., a).Most glaciers and ice caps can be found on Ellesmere, Devon, Axel Heiberg, and Meighen Islands forming the northern archipelago (Northern Cited by: [1] The Canadian Arctic Archipelago (CAA) contains the largest volume of glacier ice on Earth outside of Antarctica and Greenland.

In the absence of significant calving, CAA glacier mass balance is governed by the difference between surface snow accumulation and meltwater runoff—surface mass by:. The inter-annual relationship between the boreal winter Arctic Oscillation (AO) and summer sea surface temperature (SST) over the western tropical Indian Ocean (TIO) for the period from to is investigated.

The geometry of the bodies accords with the known reversals of the geomagnetic field during the last million years, indicating a spreading rate Cited by:
