Forth. Firth

Halliday et al. [396] have described a simple rapid graphite furnace method for the determination of lead in amounts down to 1 xg/l in polluted seawater. The filtered seawater is diluted with an equal volume of deionised water, ammonium nitrate added as a matrix modifier, and aliquots of the solution injected into a tantalum-coated graphite tube in an HGA-2200 furnace atomiser. The method eliminates the interference normally attributable to the ions commonly present in seawater. The results obtained on samples from the Firth of Forth (Scotland, UK) were in good agreement with values determined by anodic stripping voltammetry.

Temperature and salinity data from the Firth of Forth were available for the period October 1998 to September 2003, collected at intervals of approximately three months by researchers from Marlab , Aberdeen. Average monthly mean temperatures, based on a 37.1 km (20 nautical mile) grid (20 latitude by 30 longitude) are also available from Austin et al. (2006). 

Geographers such as Ptolemy Avienus abbreviated Albion to Alba. Gaelic speaking Scots, the original Celtic Britons, still refer to their Scotland (the eastern Border country and Wales) as Alba. Caledonia, from the Caledonii tribe, is the old name for Scotland north of the Firth of Forth and Clyde.
