Assessing Water Quality Improvement Strategies for Cockeast Pond, Westport, MA Using RMA2/RMA4
ABSTRACT:
Estuaries provide critical habitat, nursery grounds, and food to a variety of wildlife, including numerous species of migratory birds and fish. Estuaries also provide significant economic and ecological benefits, contributing tens of billions of dollars in goods and services annually across numerous economic sectors. However, in recent years, estuaries around the globe have become impaired, as total nitrogen (TN) concentrations in many systems have increased, degrading habitat, and causing the estuaries and their surroundings to lose their ability to sustain life. In this thesis, I examined different remediation scenarios to improve the water quality of one such estuary, Cockeast Pond. Cockeast Pond is a salt pond in Westport, MA that has become nitrogen enriched due to watershed inputs and poor tidal flushing. Studies of this estuary have documented the effects of nitrogen enrichment, mainly high rates of primary production and periodic dissolved oxygen depletion. The RMA2/RMA4 hydrodynamic model, an industry standard developed by the U.S. Army Corps of Engineers, was used to test different management scenarios for reducing TN in the system. First, the model was run for 1-year using time dependent inputs with present and altered nitrogen loading scenarios. Next, since previous work has shown that TN concentrations in Cockeast Pond differ for spring vs. summer conditions, separate steady state simulations were run to predict long-term spring and summer conditions independently. Decreased watershed nitrogen loading, increased tidal flushing, and the incorporation nitrogen removal by oyster aquaculture were each examined as possible remediation approaches for reducing water column TN levels. Scenarios were run addressing each remediation approach separately, as well as in combination to see which combinations can achieve target TN reductions. Findings suggest TN was not reduced below 0.5 mg/l during summer using the combined scenario consisting of 50% reduction in septic system discharge, 100% reduction in lawn fertilizers, and widening of the pond's tidal channel by a factor of two. However, the addition of two million oysters with this scenario did reduce the TN to below the threshold limit during the critical summer period. These results can be used to guide possible restoration efforts of the Cockeast Pond estuary, including non-traditional alternative approaches such as oyster aquaculture.

Master of Science Project Defense By: Kartik Subramaniam
- Location: > See description for location
- Cost: Free
- Contact: ECE: Electrical & Computer Engineering Department
- Description: Topic: Security in Cloud Using ECC and LSB Algorithms
Location: Lester W. Cory Conference Room, Science & Engineering Building (SENG), Room 213A
ABSTRACT:
Outsourcing of information into the cloud has become an effective trend in modern computing. Cloud computing requires that organizations trust that a service provider's platforms are secured and provide a sufficient level of integrity for the client's data. Despite the fact that cloud-based services offer many advantages, privacy of the outsourced data has always been a big concern. Data is often the most valuable of a company's assets, and it must be protected with as much vigilance as any other asset. In this project, one of the fastest growing cryptographic techniques Elliptical Curve Cryptography (ECC) and the most widely used image steganography technique Least Significant Bit (LSB) algorithm are implemented together for protecting data in the cloud. An application is designed in order to store a text file using the ECC algorithm and the cipher text obtained is inserted inside an image using the LSB algorithm to get a steganographic image. The original input text is decrypted by a registered user only after entering the right private key. Performance of the proposed system is compared with that of an existing system to showcase the strength of the proposed system.
NOTE: All ECE Graduate Students are ENCOURAGED to attend.
All interested parties are invited to attend. Open to the public.

Black Spaces Matter: Exploring the Aesthetics and Architectonics of an Abolitionist Neighborhood
- Location: Boston, MA
- Cost: NA
- Contact: Art History Department
- Description: NOVEMBER 19 - JANUARY 29
MCCORMICK GALLERY
BOSTON ARCHITECTURAL COLLEGE
320 NEWBURY STREET
BOSTON, MA 02115**
This exhibit showcases the abolitionist neighborhood near the New Bedford Whaling National Historical Park. This neighborhood, which was the home of many African-Americans, white and black abolitionists, and former slaves, provides a lens through which we may study interracial aspects of American cities. Massachusetts abolished slavery in 1783, more than 80 years before the Thirteenth Amendment; however, federal law supporting slave owners superseded this law and there were cases of slaves being "reclaimed" from Massachusetts in the years that followed. A strong network of abolitionists, both black and white, gave New Bedford its claim to fame that no slave was ever forcibly "reclaimed" from it.
New Bedford's architecture reflects a period of relative racial equality and tolerance in "the city that lit the world" during its whaling boom. This neighborhood includes a mixture of Gothic Revival, Federal, Greek Revival, and early Italianate homes, as well as modest cottages. Important historical figures, such as Fredrick Douglass and Lewis Temple, resided in these homes.
In recent years we have seen a growing body of literature on race and architecture; however, this scholarship has focused mostly on the negative side of such built environments; lacking is an in-depth exploration of the form and function of interracial neighborhoods. This exhibit celebrates the aesthetics and architectonics of a neighborhood where many former slaves lived side-by-side with the rest of the population and engaged multiple aspects of the city's interracial architecture. Through this exhibit, local New Bedford experts along with students and faculty from UMass Dartmouth and the BAC will reveal a lesser-known progressive interracial neighborhood in the United States.
Please join us on Friday, December 1, from 5:30-7:30 pm, for a special panel discussion and reception.
Black Spaces Matter is supported by a Creative Economy Fund from the Ofice of the UMass President, Perkins + Will Associates, University of Massachusetts Dartmouth, Boston Architectural College (BAC), New Bedford Historical Society, Rotch Jones Duff House and Garden Museum, and Spinner Publications.

Tayo Heuser: Paper Constructs / Exhibition at University Art Gallery / New Bedford

Tayo Heuser: Paper Constructs
Reception: AHA Night, Thursday Dec 14, 6:00 - 8:00 PM, Artist Talk 7:00 PM
Closing reception: Wednesday, January 31st, 6-7.30 pm
American, raised in Africa and Europe, Tayo Heuser's solo exhibition at UMass Dartmouth University Art Gallery in Downtown New Bedford presents a fascinating collection of abstracted works made from paper and on paper. Combining traditional techniques, multi-cultural influences, and contemporary artistic approaches, Ms. Heuser's reception will be part of AHA! Night on Thursday Dec 14, from 6 to 8 PM, with the Artist Talk at 7:00 PM.
Heuser's large scale drawings on hand made paper are invitations into the universe of geometric forms, lines and color. Their surfaces seem to breathe quietly as they invite you into the artist's meditative and delicate drawing process described by Ms. Heuser as a way to gain insight into an unconscious world where colors and geometric forms emerge. These drawings aim to represent and communicate the reverberations and energies that are released during moments of profound solace and quietude.
As a daughter of a diplomat, Tayo was surrounded by the visual language of African countries such as Tunisia, Libya, the Sudan and the Ivory Coast. This experience has brought an unusual sensibility to her work. She uses a labor-intensive paper sizing technique from the 1300's that was used for Tugras and other calligraphic texts during the Ottoman Empire. This process includes egg white, alum and burnishing with a small agate stone, resulting in a beautiful sheen whereby the ink sits on top of the paper creating a bit of multi-dimensionality.
Tayo Heuser's recent body of work took this approach even further as she created sculptures from paper. Unlike traditional sculptures, these objects are very light, yet nonetheless carrying the memory of the wood used to create them. Wrapping handmade abaca paper around a wooden support, the artist carefully cuts the paper, releases the wooden form and finally, reattaches the seams. The large installation, Window, offers a sublime wall of windows on the gallery's largest wall, drawing the viewer's eyes and leading them to reflect on his or her own state of mind.
Her new sculptures, shown here for the first time, were created during her paper-making residency in Women's Studio Workshop in NYC. This experience has freed her geometric forms to literally 'leave the frame' and to exist independently, while resting directly on the gallery wall. Similar technique appears in her series of shields, which takes handmade and hand tinted abaca paper and mounts them to hand molded acrylic, leaving the surface appearing like a wave in the ocean with the artwork unwilling to stay flat on the wall. The exhibition also includes a series of intimate drawings. The closing reception is planned for Wednesday, January 31st, 6-7.30 pm after the workshop for the UMass Dartmouth students sponsored by the Papermaking Club.
