The ocean and inland waters are two separate regimes, with concentrations in greenhouse gases differing on orders of magnitude between them. Together, they create the land–ocean aquatic continuum (LOAC), which comprises itself largely of areas with little to no data with regards to understanding the global carbon system. Reasons for this include remote and inaccessible sample locations ...

Dissolved greenhouse gas measurements (GHG) are of increasing importance for science, monitoring agencies and industry. Sensors for dissolved carbon dioxide (CO2) and methane (CH4) are applied in a growing number of applications. At the same time the number of mobile platforms deployed in the field is growing.

The CCS811 Air Quality Breakout Board is a digital gas sensor capable of sensing a wide range of Total Volatile Organic Compounds (TVOC) equivalent carbon dioxide (eCO2) with metal oxide (MOX) levels. We can thus use this sensor to identify the air quality …

To achieve the degree target, however, it would be necessary to reduce manmade carbon dioxide (CO2) emissions by 45 percent compared with 2010 levels until 2030. By 2050 at the latest, emissions would have to be net zero. In addition, it would be necessary to remove 1001000 gigatonnes of CO2 from the atmosphere during the 21st century. This corresponds to a quantity that mankind releases ...

20190207· "Only with models based on realistic quantities can future predictions be made about the quantities of the important nutrient nitrate in the lowoxygen ocean, or the amount of CO2 release taking place there," said Professor Andreas Oschlies from GEOMAR, and speaker of the SFB 754. "With their newlypresented research, the scientists involved have established a very good basis for better ...

/ Kiel. Realistic estimates show that global warming can only be kept below or 2 degrees Celsius if carbon dioxide is actively removed from the atmosphere. Storage beneath the seafloor is an option that has been investigated intensively by an international team of scientists led by the GEOMAR Helmholtz Centre for Ocean Research Kiel.

A HydroC® CO2 sensor was deployed from a pontoon at the waterfront of the GEOMAR west shore building into Kiel Fjord, Western Baltic Sea (Kiel, Germany; 54°19''"N, 010° 8''"E).

“This may cause the oceans to absorb less CO2 in the future," concludes the GEOMAR biogeochemist. And one more climaterelated function may be weakened: the production of dimethyl sulfide (DMS). This gas supports cloud formation over the oceans. Less DMS therefore means that more sunlight reaches the Earth''s surface, contributing to the greenhouse effect "These important services of the ...

21 August 2019 / Kiel. The storage of carbon dioxide (CO2) below the seafloor is one of the measures considered by the Intergovernmental Panel on Climate Change (IPCC) as a potentially significant tool to limit climate change.
