AAS is a procedure for quantitatively determining chemical element composition by measuring the absorption of optical radiation (light) by free atoms in the gaseous state. In analytical chemistry the technique is used for determining the concentration of a particular element in a sample to be analyzed such as for example the concentration of metals [..]

ACDP is a sonar that measures water current velocities at a range of depths. They can be mounted on boats or moorings for short-term surveys or attached to the seabed for long term current and wave studies.

Adamsite is an organic compound traditionally used as a chemical warfare agent. It is an arsenical diphenylaminechlorarsine, an odourless crystalline compound, usually dispersed as aerosol and which affects the upper respiratory tract. It was first synthesized in Germany in 1915 and used during World War I.

Initiated by the European Parliament and coordinated by the European Commission, the EUSBSR aims to save the sea and increase prosperity in the Baltic Sea Region while shaping the region into a regional cooperation model for the whole EU. The implementation of the strategy is financed from different EU funds in the area including the Baltic Sea Reg [..]

Bathymetry is the study of underwater depth of lake and ocean floors. The information for bathymetric maps today usually comes from an echosounder (a sonar mounted under a boat which sends a beam of sound downward at the seafloor and measures the time it takes for it to bounce off the floor and return) or from remote sensing LIDAR/LADAR systems (sa [..]

Bioaccumulation refers to the accumulation of substances such as chemicals or toxic substances in an organism that occurs when its absorption rate is greater than the rate at which the substance is lost. It can lead to chronic poisoning even if environmental levels of the toxin are not very high. In fish, bioaccumulation can be predicted by models. [..]

A biological hazard refers to a biological substance that poses a threat to the health of living organisms.

A biological marker is an indicator of a biological state. It is a characteristic that is measured and evaluated as an indicator of normal biological or pathogenic processes. Biomarkers are used to indicate an exposure to chemicals in the environment by an organism.

A blister agent, also known as a vesicant, is a chemical compound causing severe skin, eye and mucosal pain and irritation, as do many chemical warfare agents. There are three groups of blister agents: 1) Sulfur mustards (including mustard gas), 2) Nitrogen mustards, and 3) Lewisite (an early blister agent developed but not used during World War I) [..]
