Abstract Following a request from the European Commission, EFSA was asked to deliver a scientific opinion on the safety and efficacy of a feed additive consisting of an extract from the dried leaves of Hedera helix L. (common ivy extract) and thymol, when used as a sensory additive in feed for all animal species and categories except poultry ...

Sea-level response to ice sheet evolution: An ocean perspective [PDF]
The ocean's influence upon and response to Antarctic ice sheet changes is considered in relation to sea level rise over recent and future decades. Assuming present day ice fronts are in approximate equilibrium, a preliminary budget for the ice sheet is ...

Abstract Following a request from the European Commission, EFSA was asked to deliver a scientific opinion on the safety and efficacy of difructose anhydride III as a zootechnical feed additive (functional group: physiological condition stabilisers) for neonatal and female adult bovines, caprines and ovines.

Patterns in glacial-earthquake activity around Greenland, 2011–13
Glacial earthquakes are caused by large iceberg calving events, which are an important mechanism for mass loss from the Greenland ice sheet. The number of glacial earthquakes in Greenland has increased sixfold over the past two decades.

Abstract Following a request from the European Commission, EFSA was asked to deliver a scientific opinion on the assessment of the application for renewal of authorisation of betaine anhydrous (3a920) as a feed additive for all animal species. In the context of the renewal application, the applicant requested a change of the authorised specifications ...

The heterogeneous nature of Fe delivery from melting icebergs [PDF]
The micronutrient iron (Fe) can be transported from marine terminating glaciers to the ocean by icebergs. There are however few observations of iceberg Fe content, and the flux of Fe from icebergs to the offshore surface ocean is poorly constrained. Here

Insights From Two Decades of Seismicity at Columbia Glacier
Abstract We use Columbia Glacier as a case study to demonstrate how seismically cataloged calving events in Alaska can track glacier evolution over two decades. By combining this catalog—a serendipitous byproduct of earthquake monitoring—with terminus positions, bathymetry, glacier thickness, surface velocity, and environmental records, we show how ...

Systems Analysis of complex glaciological processes and application to calving of Amery Ice Shelf, East Antarctica [PDF]
Calving is a complex process subject to several cooperating atmospheric, oceanographic and glaciological forcings that vary in space and time, and whose relative effects are challenging to separate.

Massive Antarctic Icebergs May Calve at Random
The first analysis of extreme calving events in Antarctica finds no correlation with climate change, highlighting the significance of common, smaller calving events for ice loss and instability.
