The ocean is the main source of thermal inertia in the climate system. Ocean heat uptake during recent decades has been quantified using ocean temperature measurements. However, these estimates all use the same imperfect ocean dataset and share additional uncertainty due to sparse coverage, especially before 2007. Here, we provide an independent estimate by using measurements of atmospheric oxygen (O-2) and carbon dioxide (CO2) - levels of which increase as the ocean warms and releases gases - as a whole ocean thermometer. We show that the ocean gained 1.29 +/- 0.79 x 10(22) Joules of heat per year between 1991 and 2016, equivalent to a planetary energy imbalance of 0.80 +/- 0.49W watts per square metre of Earth's surface. We also find that the...

d&lt;sup&gt;13&lt;/sup&gt;C of Southern Ocean suspended organic matter during spring and early summer: Regional and temporal variability
Provedor de dados: 27

Observations are presented for stable carbon isotope abundance (&amp;#x3b4;&lt;sup&gt;13&lt;/sup&gt;C) and organic carbon and nitrogen content of suspended organic matter from the Southern Ocean (Circumpolar Current and Polar Front) during spring and early summer. The Polar Front Zone was characterized by elevated plankton biomasses and phytoplankton activity, which also increased significantly over the one-month investigation period. From the beginning of the phytoplankton bloom &amp;#x3b4;&lt;sup&gt;13&lt;/sup&gt;C values of suspended organic matter in the Polar Front were high, exceeding values predicted from the relationship with CO&lt;sub&gt;2(aq)&lt;/sub&gt; concentration observed in other areas of the Southern Ocean. Later in the season...
