Effects of upwelling duration and phytoplankton growth regime on dissolved-oxygen levels in an idealized Iberian Peninsula upwelling system [PDF]
Nonlinear Processes in Geophysics, 2020 We apply a coupled modelling system composed of a state-of-the-art hydrodynamical model and a low-complexity biogeochemical model to an idealized Iberian Peninsula upwelling system to identify the main drivers of dissolved-oxygen variability and to study

Measurements of the Suitability of Large Rock Salt Formations for Radio Detection of High Energy Neutrinos [PDF]
, 2001 We have investigated the possibility that large rock salt formations might be suitable as target masses for detection of neutrinos of energies about 10 PeV and above.

Seismic ground vibrations give advanced early-warning of subglacial floods
Nature Communications, 2020 Subglacial lakes and jökulhlaups (glacier outburst floods) are common in volcanic and glaciated environments, and can pose potential threats to communities living downstream. Here, the authors find that seismic tremor signals during subglacial floods can

Observations of significant flux closure by dual lobe reconnection [PDF]
Annales Geophysicae, 2007 We present an interval of dual lobe reconnection during which interplanetary magnetic field lines are captured by the magnetosphere by reconnecting at high latitudes in both the Northern and the Southern Hemispheres.

Solar modulation in surface atmospheric electricity [PDF]
, 2010 The solar wind modulates the flux of galactic cosmic rays impinging on Earth inversely with solar activity. Cosmic ray ionisation is the major source of air’s electrical conductivity over the oceans and well above the continents.

Ozone trends at northern mid- and high latitudes – a European perspective [PDF]
Annales Geophysicae, 2008 The EU CANDIDOZ project investigated the chemical and dynamical influences on decadal ozone trends focusing on the Northern Hemisphere. High quality long-term ozone data sets, satellite-based as well as ground-based, and the long-term meteorological ...

The structure and dynamics of a large-scale plasmoid generated by fast reconnection in the geomagnetic tail [PDF]
Annales Geophysicae, 2011 As a sequence of Ugai (2010b), the present paper studies in detail the structure and dynamics of large-scale (principal) plasmoid, generated by the fast reconnection evolution in a sheared current sheet with no initial northward field component. The
