Export fluxes in a naturally iron-fertilized area of the Southern Ocean – Part 1: Seasonal dynamics of particulate organic carbon export from a moored sediment trap [PDF]

Biogeosciences, 2015
A sediment trap moored in the naturally iron-fertilized Kerguelen Plateau in the Southern Ocean provided an annual record of particulate organic carbon and nitrogen fluxes at 289 m. At the trap deployment depth, current speeds were typically low (~ 10

Herschel/HIFI discovery of interstellar chloronium (H_2Cl^+) [PDF]

, 2010
We report the first detection of chloronium, H_2Cl^+, in the interstellar medium, using the HIFI instrument aboard the Herschel Space Observatory. The 2_(12)−1_(01) lines of ortho-H^(35)_2 Cl^+ and ortho-H^(37)_2 Cl^+ are detected in absorption towards ...

Seasonal Dynamics of Riverine Inputs in Guadeloupe (French West Indies): Insights From More Than 12 Years of Monitoring

Hydrological Processes, Volume 40, Issue 3, March 2026.
Riverine solute fluxes peak during the wet season, emphasising the role of tropical rainfall in driving nutrient delivery to the ocean. Seasonal peaks in nutrient fluxes highlight the need for longer‐term monitoring to detect potential interannual trends.

The weakening relationship between the Impact Factor and papers' citations in the digital age [PDF]

, 2012
Historically, papers have been physically bound to the journal in which they were published but in the electronic age papers are available individually, no longer tied to their respective journals.

Magma Paths of the Karthala and La Grille Volcanoes (Grande Comore) Revisited: New Evidence From Geomorphology and Geochemistry

Geochemistry, Geophysics, Geosystems, Volume 27, Issue 3, March 2026.
Abstract Grande Comore, the westernmost island within the Madagascar Comoros Volcanic (MCV) chain, hosts two juxtaposed basaltic volcanoes, Karthala and La Grille, with contrasting lava geochemical signatures and eruption frequencies. Their formation and dynamics have been explained either by a mantle plume or, more recently, as part of a ...

Polarisation and propagation of lion roars in the dusk side magnetosheath [PDF]

Annales Geophysicae, 2001
We present observations of "lion roars" obtained in the magnetosheath by the Spectrum Analyser (SA) of the Spatio-Temporal Analysis of Field Fluctuations (STAFF) experiment aboard Cluster.

Detection of a very bright optical flare from a gamma-ray burst at redshift 6.29

, 2005
In this letter we discuss the flux and the behavior of the bright optical flare emission detected by the 25 cm TAROT robotic telescope during the prompt high-energy emission and the early afterglow.

Soft X-ray analysis of a loop flare on the Sun [PDF]

, 2004
We present the results of an analysis of soft X-ray images for a solar flare which occurred on 1992 July 11. This flare, as seen in Yohkoh Soft X-ray Telescope (SXT) images was of comparatively simple geometry, consisting of two bright footpoints early ...

Frequency Extensions of Auroral Kilometric Radiation: The Key to Unlocking Earth's Radio Response to Substorms

Journal of Geophysical Research: Space Physics, Volume 131, Issue 3, March 2026.
Abstract Auroral kilometric radiation (AKR) provides a sensitive probe of magnetospheric dynamics during substorms. We analyze an extended data set of AKR bursts observed by the WIND spacecraft to investigate how the frequency structure of AKR responds to substorm onset and evolution.

The SPHERE data center: a reference for high contrast imaging processing [PDF]

, 2017
The objective of the SPHERE Data Center is to optimize the scientific return of SPHERE at the VLT, by providing optimized reduction procedures, services to users and publicly available reduced data. This paper describes our motivation, the implementation
