Prevalence and Risk Factors of Q Fever in Smallholder Dairy Farms in Kenya

open access: yesVeterinary Medicine and Science, Volume 12, Issue 4, July 2026.
Serological and molecular screening revealed widespread exposure to Coxiella burnetii in dairy cattle, linked to reproductive and herd management risk factors. Strengthened surveillance and herd‐level biosecurity are critical to reducing Q fever transmission. ABSTRACT Background Q fever is a neglected zoonotic disease of global concern.

Warm Surface Waters Dominate Melting of the Denman‐Shackleton Ice Shelf System

open access: yesJournal of Geophysical Research: Oceans, Volume 131, Issue 7, July 2026.
Abstract The ocean dynamics controlling the melting of the Denman‐Shackleton ice shelf system are investigated using a high‐resolution regional ocean‐sea ice‐ice shelf model. Our results show that basal meltwater production exhibits strong seasonal variability, driven by the ocean heat supply toward the ice shelf system, and occurs through two distinct

The evolution of the Greenland Ice Sheet from the Last Glacial Maximum to present-day: An assessment using glaciological and Glacial Isostatic Adjustment modelling [PDF]

open access: yes, 2009
In this thesis we constrain a three-dimensional thermomechanical model of Greenland ice sheet (GrIS) evolution from the Last Glacial Maximum (LGM, 21 ka BP) to the present-day using, primarily, observations of relative sea level (RSL) as well as field ...

Harbor Porpoise and Beluga Whale Habitat Use in the Saguenay‐St. Lawrence Marine Park (Canada) Revealed by a Combination of Visual and Acoustic Survey

open access: yesMarine Mammal Science, Volume 42, Issue 3, July 2026.
ABSTRACT Studying habitat use of cetaceans that spend most of their lives underwater poses challenges, prompting the use of complementary methods. Non‐invasive methods, land‐based surveys (LBS) and passive acoustic monitoring (PAM), were used to characterize occurrence patterns of beluga whales, harbor porpoises, and vessels in the Saguenay–St ...

Synchronous terminus change of East Antarctic outlet glaciers linked to climatic forcing [PDF]

open access: yes, 2013
In recent years there has been a growing trend of acceleration, thinning and retreat of ocean-terminating outlet glaciers in both the Greenland and West Antarctic Ice Sheets, resulting in an increasing contribution to sea level rise.

Are seasonal calving dynamics forced by buttressing from ice mélange or undercutting by melting? Outcomes from full-Stokes simulations of Store Glacier, West Greenland [PDF]

open access: yesThe Cryosphere, 2014
We use a full-Stokes 2-D model (Elmer/Ice) to investigate the flow and calving dynamics of Store Glacier, a fast-flowing outlet glacier in West Greenland.

Adaptive Acoustic Monitoring for Endangered Cook Inlet Beluga Whales in Complex Soundscapes

open access: yesMarine Mammal Science, Volume 42, Issue 3, July 2026.
ABSTRACT Effective conservation of the endangered Cook Inlet beluga whale (Delphinapterus leucas) requires comprehensive spatiotemporal data, yet monitoring efforts remain spatially biased, underrepresenting important southern habitats. Passive acoustic monitoring (PAM) provides the necessary broad‐scale coverage, but its expansion introduces ...

Bending Shear: The Rate-controlling Mechanism for Calving Ice Walls

open access: yes, 1989
Bending shear was observed to produce nearly vertical shear bands in a calving ice wall standing on dry land on Deception Island (lat. 63.0°S., long.

Reduced West Antarctic Ice Sheet Size During Prominent Quaternary Interglacials Constrained by Iceberg‐Rafted Debris Provenance in the Amundsen Sea

open access: yesGeophysical Research Letters, Volume 53, Issue 12, 28 June 2026.
Abstract The stability of the West Antarctic Ice Sheet (WAIS) remains a major uncertainty in sea‐level projections, and geologic records provide important constraints on its past behavior. We present 40Ar/39Ar ages of biotite and hornblende grains from iceberg‐rafted debris (IRD) in two Amundsen Sea sediment cores (PC493 and PS58/254), located south ...

The Energy Balance of Calved Ice in Lake Jökulsarlon, Iceland

open access: yesArctic, Antarctic, and Alpine Research, 2003
Abstract We describe energy fluxes involved in melting ice in the proglacial lake Jokulsarlon and the transport of thermal energy into the lake from the atmosphere and the sea. Data from earlier fieldwork and campaigns have been used to estimate the net radiation balance, the turbulent fluxes, the heat provided by inflowing seawater, and the glacial ...
