Town Of Salisbury Harbor Plan -- Phase 1, Urban Harbors Institute, University Of Massachusetts Boston

Urban Harbors Institute Publications

This document presents information developed during the first phase of the planning process to develop a Harbor Plan for the Town of Salisbury, Massachusetts. The initial phase consists of compiling and mapping existing information on natural resources, uses of the waterways and shoreline, relevant government regulatory programs and jurisdictions, identifying issues, and conducting some analyses of recreational boating-related needs. A mooring plan and mooring field delineation plan are required by the Harbor Management Plan and will be periodically updated as needed. This phase concludes with a preliminary identification of long-term goals and the development of recommendations for next steps in …

An Application For A State Designated, Federally Approved No Discharge Area For Boston Harbor, Ma, City Of Boston Environment Department, City Of Quincy Harbormaster, Urban Harbors Institute, University Of Massachusetts Boston, Charles River Watershed Association

Urban Harbors Institute Publications

The municipalities surrounding Boston Harbor are requesting that the Commonwealth of Massachusetts designate the waters of Boston Harbor as a No Discharge Area (NDA) pursuant to the Clean Water Act, Section 312(f)(3). An NDA is a body of water in which the discharge of vessel sewage, whether treated or not, is prohibited. The No Discharge Area would be called the Boston Harbor No Discharge Area.

While the waters of Boston Harbor are under the jurisdiction of a number of different municipalities, water quality issues affect the harbor as a whole. Past efforts to clean up the harbor have occurred across …

Shading Facilitates Sessile Invertebrate Dominance In The Rocky Subtidal Gulf Of Maine, Ron J. Etter, Robert J. Miller

Biology Faculty Publication Series

Dramatic shifts in community composition occur between vertical and horizontal rocky surfaces in subtidal environments worldwide, yet the forces mediating this transition are poorly understood. Vertical rock walls are often covered by lush, diverse communities of sessile suspension-feeding invertebrates, while adjacent horizontal substrates are dominated by algae, or corals in the tropics. Multiple factors, including light, sedimentation, water flow, and predation have been proposed to explain this pattern, but experimental tests of these hypotheses are lacking. We manipulated light level and predation to test whether variation in these mechanisms could be responsible for the shift in composition of sessile communities …
