Department of Geography) ; Rosell Melé, Antoni (Universitat Autònoma de Barcelona. Institut de Ciència i Tecnologia Ambientals)
In this paper we revise the application of the U₃₇ᵏ' and U₃₇ᵏ indices as sea surface temperature (SST) proxies in the Nordic Seas. In the summer of 1999 and 2000 we obtained samples of filtered particulate organic matter (POM) from surface waters (∼6 m depth) of the Nordic Seas. [...]
