The G4Foam Experiment: global climate impacts of regional ocean albedo modification [PDF]

Atmospheric Chemistry and Physics, 2017
Reducing insolation has been proposed as a geoengineering response to global warming. Here we present the results of climate model simulations of a unique Geoengineering Model Intercomparison Project Testbed experiment to investigate the benefits and ...

Diagnosing the 11‐year solar cycle's influence on the East Atlantic pattern

Quarterly Journal of the Royal Meteorological Society, EarlyView.
A previously unidentified solar‐cycle response in the East Atlantic pattern is found in late winter at lag +3 years with larger amplitude than the NAO response. A statistically significant NAO response to the solar cycle is seen in late winter at lag 0 years.

Northward shift of the Kuroshio Extension during 1993–2021

Scientific Reports, 2023
The Kuroshio Extension (KE) flows eastward at the northern boundary of the North Pacific subtropical gyre. By transporting large amounts of seawater with heat, the KE contributes significantly to the formation of sea surface temperature (SST) fields ...

Observations of Mesoscale Eddies in Satellite SSS and Inferred Eddy Salt Transport

Remote Sensing, 2021
Observations of sea surface salinity (SSS) from NASA’s Soil Moisture Active-Passive (SMAP) and ESA’s Soil Moisture and Ocean Salinity (SMOS) satellite missions are used to characterize and quantify the contribution of mesoscale eddies to the ocean ...

Contrasting the synoptic drivers of the UK heatwaves of 1976, 2003, 2018 and 2022

Weather, EarlyView.
UK summer heatwaves are dictated by the polar jet stream position and sea surface temperature (SST) variability, affecting the Summer North Atlantic Oscillation (SNAO) index. The SNAO can determine and influence the Central England Precipitation (CEP) and Central England Temperature (CET).

Hemipteran vectors of stylet‐borne plant viruses: Aphids lead the charge

Insect Science, EarlyView.
Among all sap‐feeding hemipterans, aphids stand out by far as the most important vectors of noncirculative plant viruses. Compared to whiteflies and mealybugs, aphids’ highly specialized stylet anatomy and distinct feeding behaviors contribute, together with other features of their biology, to their remarkable efficiency in transmitting stylet‐borne ...

Combining BioGeoChemical-Argo (BGC-Argo) floats and satellite observations for water column estimations of the particulate backscattering coefficient [PDF]

Ocean Science
As the second-largest carbon reservoir on Earth, the ocean regulates the carbon balance through dissolved and particulate organic carbon (POC) forms. Monitoring carbon cycle processes is key to understanding the climate system.

Information flow and the adoption of soil‐improving and water conservation measures, and household welfare: Insights from a randomized controlled trial in Uganda

American Journal of Agricultural Economics, EarlyView.
Abstract Extension services are designed to facilitate the flow of information from researchers to farmers. However, information failures continue to impede the diffusion of soil‐improving and water conservation technologies in Sub‐Saharan African countries. We use a randomized controlled trial (RCT) to examine the impact of an extension‐based campaign

A new pest recorded in Italy: The South African citrus thrips, Scirtothrips aurantii (Thysanoptera: Thripidae)

EPPO Bulletin, EarlyView.
Abstract The South African citrus thrips, Scirtothrips aurantii Faure, 1929, has been recorded in Italy for the first time. This species was recently reported in Spain and Portugal. Its presence has been confirmed in the major citrus‐growing area of Catania province (Sicily), infesting citrus trees. S. aurantii is currently included in the EPPO A1 List

The most oligotrophic subtropical zones of the global ocean: similarities and differences in terms of chlorophyll and yellow substance [PDF]

Biogeosciences, 2010
The cores of the subtropical anticyclonic gyres are characterized by their oligotrophic status and minimal chlorophyll concentration, compared to that of the whole ocean. These zones are unambiguously detected by space borne ocean color sensors thanks to
