Big big news!! After 3 years of preparation, re-designing and endless adjustments finally the prototype hyperbaric system “SeaFloor” was installed and tested in LabHorta.
This system was developed in collaboration with several experts of Portuguese research Institutes: INEGI; CIIMAR; IMAR and the SME MJ Amaral Equipamentos Industriais Lda and was financed by the FCT Project FISIOVENT with a budget of 86400 EUR.
SeaFloor is unique in various aspects:
• its 35 L volume fits a statistically suitable number of mussels
• allows long term hyperbaric manipulations as its flow rate can be regulated for up to 4 l/ min
• operates in corrosive conditions (i.e. presence of sulphide, methane, metals in seawater) as it is made of a special stainless steel and covered with a novel chemically inert fluorinated polymer: Halar.
• extended pressure resistance is provided by enforcement with carbon fibers.
Enables video-monitoring using camera-fitted borescope through the Polymethyl methacrylate (PMMA) window of the top.
• mobility and light weight enables easy on-board use

Deep-Sea Biology Symposium in Southampton
Between the 9-14 July 2006 V Costa & E Kadar will
participte at the11th Deep-Sea Biology Symposium held in
Southampton, UK.
They will present a poster (click to enlarge) & a Powerpoint
presentation entitled: "Is essential
metal requirement of the vent mussel Bathymodiolus azoricus
enhanced as compared to non-hydrothermal molluscs?"
The abstract of both works can be downloaded at the symposium's

Study of a potential “reference” population
of clams from the Lagoa de Santo Cristo, São Jorge island.
Sampling,
and dissection of clams (Ruditapes decussatus) for metal analysis
in order to determine the baseline essential metal concentrations.
