Conclusions
CONFIRMED
•97 % of T. erythraeum
• > 1000 tricomes / ml
• The warmest SST (28.5º C) in 15
years
• The warmest Tair since 1889
• Positives anomalies SLA (estability)
• High concentration of Chl a
•High NWLR (490)
• High input of dust
NON CONFIRMED
Fe++ (Dust Input)
Future: Operational service.
“HABs and HCB“ Monitoring Planning
•Sampling (week*) : BNA –ULPGC
•Microscopy: BNA –ULPGC
•Toxins (HPLC–DAD) : U.Dundee
“Regional Administration”
•Satellite monitoring real time
INM, SeaS-ULPGC
• Communication
•Dust inputs: BSC, INM
•Protection lines of buoys
•Close the beaches
•Exhaustive control of fishing and aquaculture
