In one embodiment, a system includes a memory, and a memory controller coupled to the memory via an address bus, a data bus, and an error code bus. The compressor includes a first compressor stage and a second compressor stage, the first compressor stage providing compressed refrigerant to an input of the second compressor stage. The spectral absorbance of ions such as divalent lead or copper in seawater is predominantly determined by the carbonate ion content of seawater. The adapter clamp also includes at least one connector slidably joining the body members such that the members are adapted to slide between a spread configuration wherein the members have a gap between the body members and a compressed configuration wherein the members substantially abut each other so that the toes may be inserted past the rim and into the recess of the aerosol can.
