Resumo
Various studies explore the relationship between the rising levels of CO2 and CH4 (greenhouse
gasses) in the atmosphere and climate changes, and how these increases are connected to human activities.
The escalation of these gas species may have implications for the environment. Concerning coastal systems,
the rise in greenhouse gas emissions could impact the environment through multiple pathways because the
atmosphere and superficial ocean waters also have significant exchanges. The main purpose of this work is to study Greenhouse gasses (GHG), such as CO2 and CH4, on the superficial waters of the coastal region of São
Paulo coast. The data were collected in situ on a vessel provided by the Institute of Oceanography of São Paulo
University (IOUSP). The campaign was conducted in spring 2022 (10-11 Оctober) in the south of the coast of
São Paulo state, traveling through cities with anthropogenic impacts in principal Santos city, which is located
the main port of Sul America. For these in situ measurements a portable gas analyzer Microportable Greenhouse
Gas Analyzers (LGR-ICOS ™ GLA Series) was used to detect the CO2 and CH4 spectra through the Off-Axis
Integrated Cavity Output Spectroscopy (OA-ICOS) technique.
