Lamprey watershed education and outreach

The Lamprey River Nomination Committee sought the assistance of the Piscataqua Region Estuaries Partnership (PREP) to complete an extensive and detailed information package to nominate the Lamprey River and its major tributaries to the NH Rivers Management and Protection Program. The nomination package was due at DES on June 1, 2010, was reviewed and accepted by the State Rivers Management Committee in September and forwarded to the Commissioner of DES. The nomination is now working through the NH legislature with hearings anticipated during the spring 2011 session. If passed, the bill should be signed by Governor Lynch in July of 2011. Assistance from PREP was essential for the completion of a major outreach effort to landowners along the rivers under consideration, communication with each town selec tboard, planning board and conservation commission, and with many partners and organizations throughout the watershe

Stream Assessments and Water Quality Monitoring in the Cocheco River Watershed 2001 Project

The purpose of the project is to gather data and information through volunteer water quality monitoring and stream surveys in the Cocheco River watershed. The data will be analyzed and disseminated for use in watershed management planning by the Cocheco River Watershed Coalition with the watershed communities

Black holes from CFT: Universality of correlators at large c

Two-dimensional conformal field theories at large central charge and with a sufficiently sparse spectrum of light states have been shown to exhibit universal thermodynamics. This thermodynamics matches that of AdS$_3$ gravity, with a Hawking-Page transition between thermal AdS and the BTZ black hole. We extend these results to correlation functions of light operators. Upon making some additional assumptions, such as large $c$ factorization of correlators, we establish that the thermal AdS and BTZ solutions emerge as the universal backgrounds for the computation of correlators. In particular, Witten diagrams computed on these backgrounds yield the CFT correlators, order by order in a large $c$ expansion, with exponentially small corrections. In pure CFT terms, our result is that thermal correlators of light operators are determined entirely by light spectrum data. Our analysis is based on the constraints of modular invariance applied to the torus two-point function.Comment: 18 pages. v2: minor edit

Semiclassical Virasoro Blocks from AdS3_3 Gravity

We present a unified framework for the holographic computation of Virasoro conformal blocks at large central charge. In particular, we provide bulk constructions that correctly reproduce all semiclassical Virasoro blocks that are known explicitly from conformal field theory computations. The results revolve around the use of geodesic Witten diagrams, recently introduced in arXiv:1508.00501, evaluated in locally AdS$_3$ geometries generated by backreaction of heavy operators. We also provide an alternative computation of the heavy-light semiclassical block -- in which two external operators become parametrically heavy -- as a certain scattering process involving higher spin gauge fields in AdS$_3$; this approach highlights the chiral nature of Virasoro blocks. These techniques may be systematically extended to compute corrections to these blocks and to interpolate amongst the different semiclassical regimes.Comment: 32 pages + refs. v2: fixed figure glitc

2004 Alewife Festival

On June 5, 2004, the Exeter River Local Advisory Committee (ERLAC) held the 4th Annual Exeter River Alewife Festival along the banks of the Squamscott River in downtown Exeter. Over three dozen organizations exhibited at the Festival and event organizers estimate approximately 750 people, including many children, attended the event. The purpose of the Festival was to increase awareness of the Exeter River watershed and the role it plays in the Great Bay ecosystem, as well as its role in providing drinking water, wildlife habitat, and scenic, historic and recreational resources for residents in the ten watershed towns. Funding provided by the New Hampshire Estuaries Project enabled ERLAC to print posters, banners, and newspaper advertisements announcing the event
