What is SIRENA?

SIRENA is a "what", not a "who". It's the acronym for our project to investigate the influence of the continental margin as a source of iron to the open ocean. We'll be using a multi-tracer approach to tease out the contributions from dust vs from the margin.  The fun starts in August 2008, when we'll be tagging along with Ed Boyle from MIT on a trans-Atlantic transect.  The fun continues in September in the waters between the Cape Verde Islands and the Mauritanian coast in the Eastern tropical Atlantic.  This is a region that is heavily influenced by dust deposition from the Sahara, but we think that the margin might be an additional source of iron that is advected out laterally, so this cross-shelf transect is designed to test just that.  These measurements will be conducted on the R/V Oceanus, which will be home for about 40 days!  We'll go back to Cape Verde the winter following to see whether seasons make a difference.

Cruise data and info will be posted here in the future!

SIRENA is supported by the Chemical Oceanography program at the National Science Foundation (#0726367)
