Gas chemistry characterization at Panarea shallow CO2 seeps during cruise ECO2-8

The aim was to determine the overall gas composition of benthic fluxes at the Panarea venting sites. In particular the content of CO2 and main reactive gases (i.e. H2, H2S, CH4)...

Prokaryotic abundance in natural and transplanted sediments at Panarea shallo...

Total prokaryotic cells were enumerated, via AODC method, at natural and transplanted sediments collected both at CO2-impacted sites and reference site.

Marble tiles dissolution experiment at Panarea shallow CO2 seeps from 2012-2013

To determine the long-term effect of reduced pH on calcium carbonate structures, pre-weighed marble tiles were deployed in 2012 between CO2-impacted sites and Reference site....

Recording current meter at Panarea CO2 seepage during cruise ECO2-8

As during the previous field trip, a SEAGUARD recording current meter (AADI, Norway) was used to monitor current speed and direction, temperature, salinity/conductivity,...

Sedimentary phytopigments and sediment porosity at Panarea shallow CO2 seeps ...

The amount of phytopigments (chlorophyll a and phaeopigments) were assessed for sediments profile (0 to 10 cm depth) of samples collected at CO2-impacted sites and reference...

Respiration rates and fluid flow in benthic chambers at Panarea CO2 seepage d...

Benthic chambers were deployed to measure total flux rates of oxygen consumption/production, nutrients and DIC within a defined volume of sediment and seawater. They were also...

Nutrients and geochemistry of bottom water and porewater at Panarea CO2 seeps...

Bottom waters and pore waters were collected at "natural sediments" of CO2-seep sites and reference site, and at transplantation bags.Sediment depth: negative values mean above...
