Suspended particulate organic carbon and its carbon isotopic composition in the surface water around the Antarctic Peninsula during summer 2017–2018
Abstract The concentration of suspended particulate organic carbon (POC) and its carbon isotopic composition (δ 13 C POC ) were analysed in this study with the aim of exploring the sources and factors influencing levels of POC in the surface water around the Antarctic Peninsula. The scanning electro...
