Net sea-air CO2 fluxes and modelled pCO2 in the southwestern subtropical Atlantic continental shelf during spring 2010 and summer 2011

Understanding the mechanisms behind high glacial productivity in the southern Brazilian margin

“…We reconstructed subsurface temperatures at a water depth of 100 m using the modern analog technique (MAT) following Portilho-Ramos et al (2015). The MAT was performed on the C2 software (Juggins, 2007), and the basic assumption was that the temperature of ambient seawater is the primary control on foraminiferal assemblages (Morey et al, 2005). The planktonic foraminiferal calibration dataset used here comprises 1052 surface samples from the Atlantic Ocean: from these samples, 891 were previously published in Kucera et al (2005a) and 161 from North Atlantic eastern boundary upwelling zones were previously published in Salgueiro et al (2014).…”

Ocean acidification studies and the uncertainties relevance on measurements of marine carbonate system properties

“…broa.furg.br), with studies from different research areas covering different parts of the Brazilian coastline, the open ocean areas and the western South Atlantic Ocean (e.g. Longuini et al, 2015;Cotovicz et al 2016a;Kerr et al, 2016;Ito et al, 2016;Lencina-Avila et al, 2016;Orselli et al, 2018) and the Southern Ocean (e.g. Kerr et al, 2018aKerr et al, , 2018bLencina-Avila et al, 2018) (Table 2).…”

“…The character * indicates the data that is closer to climate than weather goal, but still characterized as weather. areas (Ito et al, 2016;Orselli et al, 2018); studies of the impact of OA and other stressors in marine biota (Garrard et al, 2013;Rodríguez-Romero et al, 2014;Goulding et al 2017); and laboratory experiments (Orte et al, 2014;Scherner, et al, 2016;Schneider et al, 2018). Some examples of the BrOA studies done in the last five years associated with their classification based on the method precision are summarized in Table 2 and Figure 3.…”

<i>p</i>CO<sub>2</sub> variability in the surface waters of the eastern Gulf of Cádiz (SW Iberian Peninsula)

“…Moreover, in the coastal zone another source of CO 2 results from the net production of inorganic carbon derived from the processes of remineralization of the organic matter in the surface sediments originating from the continuous deposition of organic matter through the water column (de Haas et al, 2002;Jahnke et al, 2005). The intensity of this effect decreases towards offshore areas since the influence of primary production and the continental supplies on the deposition of the particulate organic matter are less (Friedl et al, 1998;Burdige, 2007;Al Azhar et al, 2017), which could be related to the greater effect determined by the mixing and biology processes in the coastal areas using the Olsen et al (2008) method.…”
