The Runnins Report 2010

Watershed Access Lab Projects

Fall 2009 marks the second year that all 10th grade Biology II students and their teachers joined the watershed study project initiated by AP Biology students at Seekonk High School. Students traveled to 2 sites along the Runnins River: the Burr’s Pond site and an upstream site at the home of the Masons; to assess the health of the river at these sites. This highly successful venture allowed these students to relate ecological concepts to real, hands on research. Students, with the assistance of Kim McCoy, collected and filtered water grab samples, collected macroinvertebrate samples, took pictures of their classmates …

Abbott Run Annual Study 2010

Watershed Access Lab Projects

The purpose of our study was to make certain that Abbott Run met the standards of a Class A River. We are concerned that the Abbott Run remains a Class A river because it is the source of drinking water for Pawtucket, Rhode Island.

Abbott Run is located in the Western section of North Attleborough and is within the Blackstone River Watershed. Rhode Island to the West, and Plainville and North Attleborough to the South border the river. The Watershed section that is in North Attleborough is four square miles in size.

Land use is mostly single-family residential use except …

Hanson River Watch 2009-2010

Watershed Access Lab Projects

The Indian Head River is part of the large and complex system of streams and rivers, which contribute to the South Coastal Plain Watershed. A portion of the river forms the border to the Town of Hanson from where it flows into the main stem of the North River. Further upstream, the river is called the Drinkwater which itself drains into Factory Pond directly upstream of our study site A.

Historically the Indian Head, its headwaters and tributaries provided an important fishery for alewives, shad and rainbow smelt. However, the river suffered much the same as other river systems in …

The Mashpee River: Water Quality Index & Macroinvertebrates

Watershed Access Lab Projects

The Mashpee River is a short river, flowing only 5 miles before becoming tidal and draining into Popponesset Bay. In order to determine the overall water quality of our river, we ran tests on its levels of dissolved oxygen, BOD, temperature, pH, nitrates, phosphates, turbidity, and the presence of macroinvertebrates. A low level of dissolved oxygen is a sign of pollution, but our levels were better than ideal. Healthy pH levels for most fish fall between the values 5 and 9. Our pH levels were measured at around 6, well within the healthy range. Our river also maintained stable temperatures, …

Burr’S Pond And Runnins River: An Annual Watershed Survey, 2010

Watershed Access Lab Projects

AP Biology students at Seekonk High School are required to complete an independent research project to fulfill the Ecology unit of the course during the summer prior to the course. Students must apply what they learned in their readings to a local ecosystem, Burr’s Pond which is attached to the Runnins River. Students spend time at the pond area during the summer documenting organisms, evidence of population dynamics, animal behavior, trophic levels, nutrient cycling, etc. Students put together a Burr’s Pond Summer Field Research Project Portfolio to be submitted on the first day of school. Student projects are displayed at …

Mapping The Distribution Of Electron Temperature And Fe Charge States In The Corona With Total Solar Eclipse Observations, Shadia Rifai Habbal, Miloslav Druckmüller, Huw Morgan, Adrian Daw, Judd Johnson, A. Ding, Martina Arndt, R. Esser, V. Rusin, I. Scholl

Physics Faculty Publications

The inference of electron temperature from the ratio of the intensities of emission lines in the solar corona is valid only when the plasma is collisional. Once collisionless, thermodynamic ionization equilibrium no longer holds, and the inference of an electron temperature and its gradient from such measurements is no longer valid. At the heliocentric distance where the transition from a collision-dominated to a collisionless plasma occurs, the charge states of different elements are established, or frozen-in. These are the charge states which are subsequently measured in interplanetary space. We show in this study how the 2006 March 29 and 2008 …

Total Solar Eclipse Observations Of Hot Prominence Shrouds, Shadia Rifai Habbal, Miloslav Druckmüller, Huw Morgan, I. Scholl, V. Rusin, Adrian Daw, Judd Johnson, Martina B. Arndt

Physics Faculty Publications

Using observations of the corona taken during the total solar eclipses of 2006 March 29 and 2008 August 1 in broadband white light and in narrow bandpass filters centered at Fe x 637.4 nm, Fe xi 789.2 nm, Fe xiii 1074.7 nm, and Fe xiv 530.3 nm, we show that prominences observed off the solar limb are enshrouded in hot plasmas within twisted magnetic structures. These shrouds, which are commonly referred to as cavities in the literature, are clearly distinct from the overlying arch-like structures that form the base of streamers. The existence of these hot shrouds had been predicted …

Solar Observations During A Solar Minimum Using A Small Radio Telescope, Gary Forrester

Undergraduate Review

The Sun is currently in a quiescent phase called solar minimum. We used Bridgewater State College’s (B.S.C.’s) Small Radio Telescope (SRT) to observe solar radio emission during this quiet phase and correlated our data to solar X-ray data readily available through the National Oceanic and Atmospheric Administration (NOAA). Previous observations made during a period of high solar activity (solar maximum) using one of M.I.T.’s SRTs showed that some solar radio and X-ray events were correlated, while others were not. We made observations during solar minimum and found one event where there was a correlation between radio and X-ray emission.

Regional Vs. Local Impact Of Wind On Glaciers In The Andes Mountains, Derek Ferris

Undergraduate Review

Northern Peru will face critical water resource issues in the near future as permanent ice in the Andes Mountains continues to rapidly melt. Ironically, the melt-water from these glaciers supports the culture of 100s of thousands of people living at lower elevations, particularly during the dry season, and predictions suggest some glaciers may be gone in less than 100 years. The impact of local warming of “U” shaped valleys running down the dryer western slope of the Andes range is largely disregarded in current climate model predictions because of the complexity of simulating the complex topography. Studies that compare the …

A Two-Dimensional, Linear–Elastic Model To Explain Radial Extensional Fractures, Pantheon Fossae, Caloris Basin, Mercury, Brianne Mcdonough

Undergraduate Review

In this study, two-dimensional linear elasticity theory is used to model the lithospheric stress field that produces radial extensional fractures observed at Pantheon Fossae in the Caloris Basin of Mercury. These fractures were imaged by the MESSENGER mission flyby of Mercury on January 14, 2008 and show radial fractures extending outward from a 40-kilometer impact crater named Apollodorus. Recent studies have proposed several different mechanisms to explain these fractures, including magmatic processes, central basin uplift, and stresses produced by the formation of the impact crater itself.

EΠi + 1=0: The History & Development, Dawne Charters-Nelson

Undergraduate Review

I have on occasion run across the equation in books, articles and in conversation with other mathematicians. In each of these encounters the person alluded to a fascination with this equation which links the five most important constants in the whole of analysis:

• 0 = The additive identity
• 1 = The multiplicative identity
• π = The circular constant
• e = The base of the natural logarithms
• i = The imaginary unit

Being a novice mathematician, I wondered how all these fundamental constants could end up in one equation and what it meant. Along with this thought came the realization that …
