Global ocean colour algorithms, used to extract chlorophyll concentration in the
ocean surface, normally overestimate pigment values in coastal regions, due to
optical interference of water components. The objective of ...

In waters surrounding James Ross Island (JRI),
which is generally inaccessible, high chlorophyll-a concentration
[Chla] can often be detected during summer
periods by ocean color imagery. The region is influenced
by a ...

The marine diatom Chaetoceros cf. wighamii has been investigated for its potential use as food in mariculture. In this work,
we investigated temperature (20, 25, and 30 8C), salinity (25 and 35) and carbon dioxide addition ...
