Mossman2 127 Harding Avenue, Amherst, Nova Scotia B4H 2A8, Canada departm ent of Physics, Engineering and Geoscience, Mount Allison University, 67 York Street, Sackville, New Brunswick E4L 1E6, Canada Date Received April 27, 1998 Date Accepted December 15,1998 Vigorous quasi-equilibrium conditions characterize interactions between land and sea in macrotidal regions. Ephemeral on the scale of geologic time, estuaries around the Bay of Fundy progressively infill with sediments as eustatic sea level rises, forcing fringing salt marshes to form and reform at successively higher levels. Although closely linked to a regime of tides with large amplitude and strong tidal currents, salt marshes near the Bay of Fundy rarely experience overflow. Built up to a level about 1.2 m lower than the highest astronomical tide, only very large tides are able to cover the marshes with a significant depth of water. Peak tides arrive in sets at periods of 7 months, 4.53 years and 18.03 years. Consequently, for months on end, no tidal flooding of the marshes occurs. Most salt marshes are raised to the level of the average tide of the 18-year cycle. The number of tides that can exceed a certain elevation in any given year depends on whether the three main tide-generating factors peak at the same time. Marigrams constructed for the Shubenacadie and Cornwallis river estuaries, Nova Scotia, illustrate how the estuarine tidal wave is reshaped over its course, to form bores, and varies in its sediment-carrying and erosional capacity as a result of changing water-surface gradients.

The Lady Crab (Ovalipes ocellatus), mainly found south of Cape Cod and in the southern Gulf of St. Lawrence, is reported from an ocean beach on the north shore of Massachusetts Bay (42°28'60"N, 70°46'20"W) in the Gulf of Maine. All previ- ously known Gulf of Maine populations north of Cape Cod Bay are estuarine and thought to be relicts of a continuous range during the Hypsithermal.

CROIX RIVER UPDATE Joint Tribal Council of the Passamaquoddy Tribe passes St. Croix River Alewife Resolution Citing the vital linkages that sea-run alewives create in the food chain of the St. Croix River, Passamaquoddy Bay and the Bay of Fundy, members of the Joint Tribal Council of the Passamaquoddy Tribe voted unanimously to pass a resolution that calls for reopening the St. Croix Rivers for alewives. !e resolution states that sea-run alewife are a vital link in the food chain of the St. Croix River that sustained the Passamaquoddy for thousands of years, “without which we may not have survived.” !e Joint Tribal Council resolution supports the June 14, 2012 Passamaquoddy Chief’s Declaration of a State of Emergency within the St. Croix River, and calls for overturning Maine’s 1995 law that blocks alewives from the St. Croix. In early June 2012 members of the Schoodic Riverkeepers advanced the Passamaquoddy river restoration e"ort with a 100-mile sacred run up the St. Croix River, a run that mirrored the annual trek of native alewives. !e route extended from Pleasant Point, near Eastport, to Mud Lake Stream, a 4,000-year-old ancestral #shing site for the Passamaquoddy at the head of Spednic Lake. Maine Rivers has been working for nearly a decade on advocacy e"orts to reopen the St. Croix River and applauds this recent decision of the Joint Tribal Council.

  • 'Status Review for Anadromous Atlantic Salmon (Salmo Salar) in The
    A Technical Letter Review of the ‘Status Review for Anadromous Atlantic Salmon (Salmo salar) in the United States’ April 25-May 15 by T.L. Marshall CIE Reviewer Pictou, NS Canada May 15, 2006 Executive Summary The ‘Status Review for Anadromous Atlantic Salmon (Salmo salar) in the United States’ (Fay et al. 2006) represents a considerable effort by a number of professionals utilizing their own expertise and scientific information from over 600 literature citations. It is an objective assessment of possible distinct population segments (DPSs), the status of remnant and hatchery supported populations of Atlantic salmon in Maine and an assessment of 48 threats to their existence. Concerns are raised about the utility of some of the genetic material important to the delineation of the northern boundary of the Gulf of Maine (GOM) DPS. A few additional literature citations are proposed to embellish the text and some minor discrepancies were noted between material in the text and the literature from which it originated. For the most part, the information and analyses within the ‘Status Review’ supports delineation of the Long Island Sound (LIS), Central New England (CNE) and GOM DPSs. The bounds of the CNE, LIS and southern boundary of the GOM DPS rely heavily on expert opinion; the inclusion of the Penobscot population in the DPS is well founded. There is however, insufficient information to convincingly redefine the northern boundary of the GOM DPS and it is recommended that additional genetics from southwestern and western New Brunswick be obtained to verify the proposed boundary. Maine populations of wild Atlantic salmon are nearing extirpation; continued changes in land use, climate, marine ecosystem and the level of concern expressed regarding the loss of genetic diversity and fitness within the hatchery program suggest that the time-line for extinction of hatchery and wild components could be less than forecast.
