The discrimination of harmful algal blooms (HABs) from space would benefit both the capability of early warning systems and the study of environmental factors affecting the initiation of blooms. Unfortunately, there are no published techniques using global monitoring satellite sensors to distinguish the resulting subtle changes in ocean colour, so in situ sampling is needed to identify the spec...

Understanding oceanic primary production on a global scale can be enhanced by methods that are able to automatically track phytoplankton blooms from color satellite images. In this paper, unsupervised clustering and rule learning are combined to track green river, a plume of discolored water that forms every March-May offshore along the edge of the west Florida Shelf, from the Sea Viewing Wide ...

The long distance movement of marine turtles is one of the wonders of the natural world, with recapture techniques showing how some species move thousands of kilometers across the ocean (Meylan, 1995). The Mid-Atlantic serves as a host environment for a number of sea turtle species that encompasses their seasonal migration routes. Currently, out of the six turtle species all are labeled as eith...

Within the framework of the European MFSTEP project, an advanced multivariate sequential data assimilation system has been implemented to assimilate real chlorophyll data from the Sea-viewing Wide Field-of-view Sensor (SeaWiFS) into a threedimensional biochemical model of the Eastern Mediterranean. The physical ocean 5 is described through the Princeton Ocean Model (POM) while the biochemistry ...

We are grateful to you for your very positive and constructive comments. Following the helpful suggestions from you and another reviewer, we believe our manuscript has been modified significantly. Below are our replies to your comments. RC = Referee’s Comments; AR = Authors’ Response RC 1: Why the SeaWiFS period is limited to 1997-2007 only? Good quality observations are available at least unti...

Various approaches have been proposed to estimate surface ocean chlorophyll a concentrations (Chl, mg m -3 ) from spectral reflectance measured either in the field or space, each with its own strengths and limitations. Here, we develop machine learning approach reduce impact of noise improve alg...
