Sustained harmonic tremor signals were recorded by the seismographs of the German Neumayer Base seismological network in western Dronning Maud Land, Antarctica. These tremor episodes, lasting up to 16 hours, were recorded up to 820 kilometers from the source. Their spectra show narrow peaks with fundamental frequencies ranging from 0.5 to 6 hertz, more

Use of satellite data for detecting icebergs and evaluating the iceberg threats
Te methods of satellite monitoring of dangerous ice formations, namely icebergs in the Arctic seas, representing a threat to the safety of navigation and economic activity on the Arctic shelf are considered.

Tracking B-31 iceberg with two aircraft-deployed sensors [PDF]
Icebergs are a natural hazard to maritime operations in polar regions. Iceberg populations are increasing, as is the demand for access to both Arctic and Antarctic seas.

How do icebergs affect the Greenland ice sheet under pre-industrial conditions? – a model study with a fully coupled ice-sheet–climate model [PDF]
Icebergs have a potential impact on climate since they release freshwater over a widespread area and cool the ocean due to the take-up of latent heat.

Automatic Detection of Small Icebergs in Fast Ice Using Satellite Wide-Swath SAR Images
Automatic detection of icebergs in satellite images is regarded a useful tool to provide information necessary for safety in Arctic shipping or operations over large ocean areas in near-real time.

Iceberg drift and melting rates in the northwestern Weddell Sea, Antarctica: Novel automated regional estimates through machine learning [PDF]
Global warming and its consequences on polar regions have been thoroughly discussed in recent times. One of those consequences is the freshwater flux and the associated cooling and freshening that result from iceberg melting. Despite the potential impact,

SAR Ship–Iceberg Discrimination in Arctic Conditions Using Deep Learning
Maritime surveillance of the Arctic region is of growing importance as shipping, fishing and tourism are increasing due to the sea ice retreat caused by global warming. Ships that do not identify themselves with a transponder system, so-called dark ships,

I palpated a lump in my epigastrium nine months to the day after delivering my third child when I was 43. I was not alarmed since I had had an easy pregnancy and returned to work two months later as a consultant pathologist. I felt well. True, I was tired, but who is not with a full time job and three children, especially a small baby who still woke me

A hybrid ice-mélange model based on particle and continuum methods [PDF]
Ice mélange, a composite of sea ice and icebergs, can have a major influence on sea-ice–ocean interactions. However, ice mélange has not been represented in climate models because numerically efficient realizations do not exist.

Melting and fragmentation laws from the evolution of two large Southern Ocean icebergs estimated from satellite data [PDF]
The evolution of the thickness and area of two large Southern Ocean icebergs that have drifted in open water for more than a year is estimated through the combined analysis of altimeter data and visible satellite images.
