Geochemical parameters were measured at two CO2 sites and one non-CO2-impacted site near the island of Panarea (Italy). All sites were located between ~15 and 20 m water depth at a temperature of 19°C. 0-values refer to "below detection limit". DIC, total alkalinity and pH were measured ex situ after sample recovery.sediment depth : negative values mean above seafloor
In situ instruments were deployed at two CO2 sites and a non-CO2-impacted site near the island of Panarea (Italy). All sites were located between ~15 and 20 m water depth at a temperature of 19°C.
As during the previous field trip, a SEAGUARD recording current meter (AADI, Norway) was used to monitor current speed and direction, temperature, salinity/conductivity, pressure, turbidity and oxygen concentrations within the water column at CO2-seep sites and reference site.
Latitude/Longitude extracted from DSHIP.Data acquisition was performed using a multibeam sonar system Simrad EM-122 from Kongsberg. Raw data are delivered within Simrad current multibeam vendor format.SIMRAD raw data can be processed i.e. with the software packages CARIS HIPS/SIPS, Caraibes, QPS Qimera or with the open source software package MB-System (http://www.ldeo.columbia.edu/res/pi/MB-System/).These data should not be used for navigational purposes.

A climatically induced acceleration in ocean‐driven melting of Antarctic ice shelves would have consequences for both the discharge of continental ice into the ocean and thus global sea level, and for the formation of Antarctic Bottom Water and the oceanic meridional overturning circulation. Using a novel gas‐tight in situ water sampler, noble gas samples have been collected from six locations beneath the Filchner Ice Shelf, the first such samples from beneath an Antarctic ice shelf....
Increases in CO2 atmospheric concentrations are expected to lead to multiple and possibly opposing effects over crop performance. The paper uses a global economic model (RESCU-Water) to analyse the impacts of changes in climatic conditions and CO2 fertilisation on crop output and on the pressure over water resources coming from irrigation. RESCU-Water is built on a Computable General Equilibrium Framework and distinguishes between the rainfed and irrigated production of eight crop classes. Irrigation is introduced...
