This article was written 20 years ago. During that time right whales have moved northward and the presence of Phalaropes has been "up and down" according to the few reports we have received. Is anyone aware of recent studies?
The Phalarope is Fundy's "canary" ... and it's dead or dying.

Atlantic salmon swim to forefront of science
By JOHN McPHEE Environment Reporter, Halifax Chronicle-Herald
Thu. Dec 10, 2010
A genetically modified Atlantic salmon escapes from a fish farm into a river.
But it doesn’t live long enough to enjoy its freedom. Because the salmon isn’t eating a particular feed, a "kill gene" kicks in and it dies.
It may sound like science fiction but researchers are well on their way to this kind of genetic tweaking, said Fred Whoriskey, of the Atlantic Salmon Federation, in an interview Wednesday.
Genome mapping and research will eventually open up a wide array of biological tools. Most of them

The Canadian National Fire Database (CNFDB) is a collection of forest fire data from various sources; these data include fire locations (point data) and fire perimeters (polygon data) as provided by Canadian fire management agencies (provinces, territories, and Parks Canada). Fires of all sizes are included in the database, but only those greater than 200 hectares in final size are shown in the map above — these represent a small percentage of all fires but account for most of the area burned (usually

JOB: Second Posting - Postdoctoral fellow position - Ecologically and biologically significant areas for large predators in the Estuary and Gulf of St. Lawrence based on 25 years of survey, biologging and environmental data
The Department of Fisheries and Oceans (DFO) is responsible for the conservation and management of marine mammals in Canadian waters. A post-doctoral candidate is sought to develop species distribution models based on a large dataset of observations obtained from aerial and boat surveys conducted during the last 25 years in eastern Canada, in particular in the estuary and the gulf of the St Lawrence. The candidate will help collate relevant environmental data that could be associated with the occurrence of several species including the endangered blue whale, fin whale, right whale and other large predators. He/She will also benefit from information collected from bio-logging devices that were attached to several whale species. The predictive models will be used to identify important habitats of
WHALES: New publication: WhaleMap: a tool to collate and display whale survey results in near real-time
My co-authors and I have developed an open source software tool called WhaleMap (available at whalemap.org) to collate and display whale survey results in near real-time. It is described in our recent publication in the Journal of Open Source Software:

On behalf of my co-authors, I would like to announce a recent peer-reviewed publication on projecting right whale habitat suitability in 2050.
North Atlantic right whales (Eubalaena glacialis) are critically endangered, and recent changes in distribution patterns have been a major management challenge. Understanding the role that environmental conditions play in habitat suitability helps to determine the regions in need of monitoring or protection for conservation of the species, particularly as climate change shifts suitable habitat. This study used three species distribution modeling algorithms, together with historical whale abundance data (1993–2009) and environmental covariate data, to build monthly ensemble models of past E. glacialis habitat suitability in the Gulf of Maine. The model was projected onto the year 2050 for a range of climate scenarios. Specifically, the distribution of the species was modeled using generalized additive models, boosted regression trees, and artificial neural networks, with environmental covariates that included sea surface temperature, bottom water temperature, bathymetry, a modeled Calanus finmarchicus habitat index, and chlorophyll. Year-2050 projections used downscaled climate anomaly fields from Representative Concentration Pathway 4.5 and 8.5. The relative contribution of each covariate changed seasonally, with an increase in the importance of bottom temperature and C. finmarchicus in the summer, when model performance was highest. A negative correlation was observed between model performance and sea surface temperature contribution. The 2050 projections indicated decreased habitat suitability across the Gulf of Maine in the period from July through October,with the exception of narrow bands along the Scotian Shelf.The results suggest that regions outside of the current areas of conservation focus may become increasingly important habitats for E. glacialis under future climate scenarios.

Disappearing Giants tells the story of one of the most endangered large whales in the oceans today, from the whaling history for which it is named, to the most up-to-date research efforts and population status. Illustrated throughout with beautiful photos, it describes how individual right whales are identified, how they feed, migrate, and face the challenges of life in the industrialized North Atlantic Ocean. The authors, long-time right whale researchers from the Anderson Cabot Center for Ocean Life at New England Aquarium in Boston, hope this book will bring awareness to this wondrous but threatened whale species and the tremendous efforts being taken to help North Atlantic right whales avoid extinction and thrive far into the future.

The St. Croix River and its estuary has a long history of heavy commercial use, the impacts of which can still be observed in the waters and sediments of the watershed, including western Passamaquoddy Bay. Additionally, the marine and freshwater flora and fauna has been diminished significantly and for many decades anadromous fish species, in particular, have had restricted access to their up-river spawning areas.
In the 1960s, the Woodland mill dumped black liquor directly into the river for nearly 10 years causing the virtual death of the river. Since this practice was brought to an end, the river has

With a little imagination, the image of the stone stack below Campobello’s Friar’s Head reveals an “Old Friar.” A Passamaquoddy legend speaks of the stack as a young Indian maiden, turned to stone while awaiting the return of her lover. The cracks in the “Old Friar” indicate he is likely to loose his head in the not too distant future.
