More than 1400 precipitation samples were collected weekly from 5 sites in Nova Scotia between 1978 and 1987. High concentrations of H+, non-marine SOinf4sup=(*SO4) and NOinf3sup-were observed in 1978 and 1986. In 1983, concentrations of all three pa

Although water chemistry of precipitation and lakes in Nova Scotia is dominated by C1 from sea salt, correction for marine influence reveals that the dominant anion in acidified lakes is SO4. Atmospheric deposition of non-marine SO4 (SO4) and NO3- fo

Pollen analysis of a core from a postglacial raised bog at the head of the Annapolis River valley, Kings County, Nova Scotia, has revealed the presence of 5 periods of peat growth. These periods of peat growth are recognized by the occurrence of a li

A peat deposit exposed in a wave-cut cliff on the island of Martha9s Vineyard, Massachusetts (31 degrees 259N., 70 degrees 309W.), has been sampled for radiocarbon and pollen content. The section is 2.29 m long, including 12 cm of till at the base. T

Water samples were collected from 234 Nova Scotian lakes during the summers of 1981–1984. Samples from near-surface and mid-depth were composited to yield a single descriptive analysis for each lake. Median pH for the lakes was 5.37 (arithmetic mea

During the summers of 1981–1984, 19,714 fish (23 species) were netted in 234 Nova Scotian lakes. Surface and mid-depth water samples were also analyzed for major ions, metals, and DOC. Lakewater pH varied from 4.4 to 7.7, including eight lakes whic
