Molecular Weight Fractions

Seasonal changes in profiles of both UV absorbance and phenolic material versus salinity were observed in some estuarine and coastal waters of the Gulf of Maine. Profiles of riverine UV-absorbent and phenolic materials were seasonally invariant, with slight losses from high molecular weight fractions during estuarine mixing. In estuaries containing significant populations of fucoid macroalgae, exudation by the macroalgae increased levels of these parameters by as much as threefold. These increases showed a strong seasonal pulsing, following water temperature. This pulsing was detectable in seasonal transects of adjacent shelf waters.

In the summers of 1966 and 1967, very low surface temperatures, about 11 C, and weakly stratified water occurred along the western coast of the Gulf of Maine at Cape Nedick, in the Sheepscot River, and off Vinalhaven Island at the mouth of Penobscot Bay. Moderately low temperatures, about 13 C, were found often between the islands of Casco Bay. These low temperatures indicate an active vertical mixing, associated with tidal currents, that transports water warmed at the surface downward and cold water upward.Where tidal mixing is reduced, offshore from Cape Ann and in the landward confines of Casco Bay, surface temperatures over 17 C and pronounced stratification occurred. When these high temperatures were observed off Cape Ann, the weather was sunny and calm, or a light wind caused very little mixing. Within Casco Bay temperatures of 17 C or more were observed during a period when fogs were prevalent, allowing heating in clear spells in the daytime and a minimum of cooling at night.

First Time

Examination of new meristic data on sand lance (Ammodytes spp.) populations in Newfoundland coastal waters using a combination of discriminant function and modal analyses demonstrates for the first time that co-occurrence is a common feature of the distribution of the two species (A. dubius and A. americanus) provisionally considered to exist in the Northwest Atlantic. In addition, the consistency in the meristic counts of A. dubius between the offshore and inshore samples and the postulated spawning of A. dubius in Newfoundland coastal waters provides good evidence that A. dubius is reproductively isolated from A. americanus. Reanalysis of published data on the vertebral composition of sand lance in the Northwest Atlantic confirms the co-occurrence of A. americanus and A. dubius in inshore areas from West Greenland southwards to the Gulf of Maine. These new analyses taken together with a review of the major distinguishing characteristics of sand lance species in the North Atlantic waters lead us to conclude that the heterogeneous assemblage of sand lance found inshore from West Greenland southwards and offshore from Georges Bank southwards and which has traditionally been classified as A. americanus belongs to a single trans-Atlantic species, A. marinus.
