A Review of Ice and Tide Observations in the Bay of Fundy
A tlantic Geology 195 A review of ice and tide observations in the Bay of Fundy ConDesplanque1 and David J. 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. -

FROM THE TRANSACTIONS OF THE ROYAL SOCIETY OF CANADA THIRD SERIES—1914 VOLUME vin An Organization of the Scientific Investigation of the Indian Place«nomenclatiire of the Maritime Provinces of Canada by W. F. GANONG. M.AHBb.E OTTAWA PRINTED FOR THE ROYAL SOCIETY OF CANADA 19 14 Transactions of The Royal Society of Canada SECTION II SERIES III DECEMBER 1914 VOL. VIII An Organization of the Scientific Investigation of the Indian Place- nomenclature of the Maritime Provinces of Canada, (Fourth Paper). By W. F. GANONG, M.A., Ph.D. (Read by Title May 27, 1914.) This paper is identical in aim and method with its three pre decessors, which were published in the immediately foregoing volumes of these Transactions. In a word, I am trying to apply the principles of scientific analysis to a very interesting subject especially prone to doubt and error. The comparative method which I use, explained in the introduction to the first paper, is proving wonderfully successful in solving the problems, as this paper will further illustrate. For convenience of reference I may add that the former papers made analysis of the names Oromocto, Magaguadavic, Upsalquitch, Manan, Nepisiguit, Kouchibouguac, Anagance, Wagan, Pokiok, Penniac, Bocabec, Pentagoet-Penobscot, Pohenegamook, and Cobs- cook, and used the roots thus made available in the analysis of a good many other words, both existent and extinct, of lesser importance. Of these extinct Indian names,—indigenous to the country, ap propriate to the places, and often reducible to a highly pleasing form, —the greater number may be revived to obvious advantage when additional place-names become needed in future; and I have tried to suggest simplified and softened forms for such purpose. -

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. The population reported here is likely a recent local habitat expansion. Key Words: Lady Crab, Ovalipes ocellatus, Gulf of Maine, distribution.

FALL 2012/ Winter 2013 THE NEWSLETTER OF MAINE RIVERS ST. 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.

Setting the Stage for a Course Change at Popham Beach, Phippsburg
Setting the Stage for a Course Change Maine Geological Survey Maine Geologic Facts and Localities February, 2011 Setting the Stage for a Course Change at Popham Beach, Phippsburg 43° 44‘ 2.36“ N, 69° 47‘ 39.29“ W Text by Stephen M. Dickson Maine Geological Survey, Department of Agriculture, Conservation & Forestry 1 Setting the Stage for a Course Change Maine Geological Survey Introduction Popham Beach in Phippsburg, Maine has changed dramatically in the last two decades. As regular visitors to the beach have observed, the beach and dunes are different from one year to the next. In 1990 the beach was backed by an enormous dune field and visitors walked long paths to reach the shoreline. Even in 2005 there were large dunes in the area of Center Beach (Figure 1). Maine Geological Survey From Maine Office Maine of GIS Office From Figure 1. Location map of Popham Beach State Park, adjacent beaches, and water bodies. Note the background air photo was taken in 2005 and shows a large vegetated dune field near Center Beach. The sand bar from the park out to Fox Islands is called a tombolo by geologists. Maine Geological Survey, Department of Agriculture, Conservation & Forestry 2 Setting the Stage for a Course Change Maine Geological Survey Introduction By 2010 the shoreline was hundreds of feet closer to the parking lot and encroaching on a new bath house. In addition, the last few years have seen hundreds of large pitch pine trees topple onto the beach as a result of erosion driven by the Morse River cutting a long and sinuous path in an easterly direction into the state park before turning south to reach the ocean. -

It has a large natural dune system and a long stretch of natural beach composed of fine- to medium-grained sand. During the summer, the park is so popular that the parking lot can fill with cars by mid-morning. Views offshore from the park are scenic with several islands including Seguin Island with its high lighthouse. Aerial 2006 Photo, Aerial Northstar Maine Geological Survey Photo by David A.
