Remote influence of Interdecadal Pacific Oscillation on the South Atlantic meridional overturning circulation variability

Geophysical Research Letters, 2016
This study explores potential factors that may influence decadal variability of the South Atlantic meridional overturning circulation (SAMOC) by using observational data as well as surface‐forced ocean model runs and a fully coupled climate model run ...

Multi‐Country‐Multi‐City Characterisation of Heat Stress and Exposure in Africa

International Journal of Climatology, EarlyView.
This study provides the first continent‐wide, grid‐specific assessment of heat stress trends in Africa, revealing a sharp rise in multi‐scale extreme heat episodes and shifting population exposure. Findings highlight urgent implications for urban planning and climate adaptation.

In situ imaging of a kleptoplastidic ciliate thin layer indicates traditional sampling underestimates oceanic mixotroph biomass

Communications Earth & Environment
Planktonic mixotrophs, including ciliates, are abundant, yet understudied, mediators of primary and secondary production in aquatic food webs. Here, we report high-resolution in situ observations of a thin layer—a vertically limited patch of high ...

Location-Aware Source Routing Protocol for Underwater Acoustic Networks of AUVs

Journal of Electrical and Computer Engineering, 2012
Acoustic networks of autonomous underwater vehicles (AUVs) cannot typically rely on protocols intended for terrestrial radio networks. This work describes a new location-aware source routing (LASR) protocol shown to provide superior network performance ...

Addressing the World War 2 Warm Anomaly in HadSST.4.2.0.0

International Journal of Climatology, EarlyView.
We present an update to the Hadley Centre Sea‐Surface Temperature dataset (HadSST.4.2.0.0) that addresses residual warm bias during the Second World War (WW2). Using a quantitative definition of the WW2 warm anomaly we identify Engine Room Intake (ERI) bias corrections as the dominant factor in HadSST4, and use this to propose new constraints on ERI ...

Long‐Term Variability and Spatial Differentiation of the Frost‐Free Period in Iceland

International Journal of Climatology, EarlyView.
Warming in Iceland (May–September) is expressed as fewer Tmin < 0°C days in the interior and more Tmin > 0°C days along the coasts. ABSTRACT Climate change in subarctic regions leads to significant transformations in thermal conditions; however, the long‐term variability of the frost‐free season (FFS)—and consequently, the growing period—remains poorly

Characterisation of Drought and Wet Events in the Paraíba do Sul River Basin—Brazil

International Journal of Climatology, EarlyView.
Trend analysis identified statistically significant reductions in precipitation (at the 5% significance level) at specific pluviometric stations in São Paulo and Rio de Janeiro, while other areas, mainly in Minas Gerais, experienced significant increases in annual and seasonal rainfall, particularly during summer and spring. These significant trends at

Researchers explore Arctic freshwater\u27s role in ocean circulation [PDF]

, 2000
A critical, but insufficiently understood, component of global change is the influence of Arctic freshwater input on water mass exchange between the Arctic Ocean and Atlantic and Pacific Oceans.

Tropicalization of the Temperate Zone: Spatiotemporal Variability of Winter Warming and Declining Freeze Days Across the United States

International Journal of Climatology, EarlyView.
Unique characteristics of winter daily minimum (Tmin) and maximum (Tmax) temperatures and freeze days across the conterminous United States from 1952 to 2024 are examined. Results show spatial heterogeneity in Tmin/Tmax warming rates across the tropical‐temperate transition zone in the southeastern United States, and that the highest temperature on the

Early deglaciation history of the southeastern Baffin Island shelf (Eastern Canadian Arctic Archipelago)

Journal of Quaternary Science, EarlyView.
ABSTRACT During the last glacial period, the Laurentide Ice Sheet (LIS) was the largest terrestrial ice sheet on Earth. Its evolution since the Last Glacial Maximum profoundly influenced Earth's geodynamics and surface processes. Investigating the past dynamics of the LIS provides critical insights into how contemporary ice sheets may respond to ...
