2- HABs Monitoring programmes in Oman
Harmful Algae blooms Monitoring Programme in Oman:
Project of HABs Monitoring: 2008-2012 ASSESSMENTS OF MESOSCALE PHYSICAL-
BIOLOGICAL INTERACTIONS ALONG THE COAST OF OMAN AS THE BASIS FOR
UNDERSTANDING THE PERIODIC FISHERIES. :
Activities of the Projects
organization and compilation of a database: The Database software already
establish (data were already collected from Germany, Oman and Ukraine).
Database software will presented in this presentation
Remote sensing data extraction: ROPME and other Satellite images were collected
and organized for Chlorophyll a, current, DO, Wind, Salinity, temp. …..etc.
Different satellite images and modeling will presented in this presentation.
• The organization of algal and bacterial culture collection of species that is
responsible for HABs events were collected and analyzed
(for bacteria not yet analyzed) .

Data Regarding HABs in 2008-2009 were reported and analyzed.

DEVELOPMENT OF A MONITORING, MANAGEMENT AND
RESEARCH PROGRAM FOR RED TIDES IN THE SULTANATE OF OMAN
