We anticipate the focus of the two days will be to review data and TAC discussions, especially related to factors affecting overall water clarity as well as eelgrass health. Below are anticipated presentations for each of the days. As always, everyone is welcome to listen and/or participate.

  • May 9th – Portsmouth Public Library 10 AM to 2 PM – presentations from Dr. Fred Short and the Municipal Coalition.
  • May 10th – DES Coastal Program Office – Pease 9 AM to 12:30 PM – hearing from external advisors Jud Kenworthy, Ken Moore, and Chris Gobler.

Light snacks and beverages will be provided; however please bring your own lunches, if desired.

Please remember that TAC meetings are an “open membership” committee meaning anyone interested in the topic of estuarine ecosystems is welcome to attend, listen and participate.


Slides and Notes from March 28th, 2017 TAC Meeting


The purpose of TAC Updates and “Thoughts from the Coastal Scientist” is to summarize information (facts and data) from meetings and to articulate other questions, concepts, and connections that the TAC is considering. The information is intended only to help advance TAC discussions and is NOT intended to be used by an individual or group as final or conclusive statements. All information presented through this TAC page during the State of Our Estuaries report development is considered preliminary until it is published by PREP in December 2017.

  2. The 2013 Environmental Data Report; (this is the 200+ page report that formed the basis for the shorter report.)
  3. TAC Decision Making Framework

A Bit of Background…

The Purpose of the TAC is to serve as an advisory committee of experts to discuss and advise on technical, science-based issues related to the estuary program, the State of Our Estuaries Report, and the implementation of the CCMP.

TAC Responsibilities include:

  • Provide advice regarding overall science and technical issues for programs, legislation, State of Our Estuaries reports and other projects as needed;
  • Review technical documents for accuracy and providing feedback;
  • Recommend forming and disbanding new TAC subcommittees and technical workgroups as needed with regard to addressing the overall needs expressed in the CCMP or that emerge during TAC meetings or technical review work;
  • Identify emerging issues and resource management needs;
  • Assist in the synthesis of the State of Our Estuary proceedings and reports;
  • Facilitate communication and collaboration among other specialized scientists or committees in the region;
  • Help to raise local, state and national awareness for the uniqueness and environmental importance of the Great Bay and Hampton-Seabrook estuaries; and to
  • Assist in identifying funding opportunities to address science needs and advance overall PREP and any regional science agendas.

The Composition of the TAC is completely open. Regular TAC attendees will be those scientists that PREP is working with to obtain information about the ecosystem as well as public agency resource managers, municipal planners and engineers and other technical stakeholders.

A Message From PREP’s Coastal Scientist, Kalle Matso

PREP’s mission is to monitor, protect and restore the Great Bay and Hampton-Seabrook estuaries. Both of these estuaries have been designated as “estuaries of national significance.” PREP’s Technical Advisory Committee (TAC) plays a critical role in ensuring that discussions about the estuaries are based on sound science.

The TAC proceess is now underway for an important phase: the lead-up to the release of our 2018 State of Our Estuaries Report. This report is a measurement of progress for PREP toward reaching the goals and objectives outlined in the Comprehensive Conservation and Management Plan, which is our management plan for the watershed. Please visit this site often for updates during this important time.

Whenever you have questions, please don’t hesitate to contact me.

PREP is part of the U.S. Environmental Protection Agency’s National Estuary Program, a joint program between local, state and federal agencies established under the Clean Water Act with the goal of protecting and enhancing nationally significant estuarine resources. PREP is supported in part by an EPA matching grant and is housed within the School of Marine Science and Ocean Engineering at the University of New Hampshire.
