Sei+Ii Information Integration Through Events, Mary-Kate Beard-Tisdale
Sei+Ii Information Integration Through Events, Mary-Kate Beard-Tisdale
University of Maine Office of Research Administration: Grant Reports
Many environmental observations are collected at different space and time scales that preclude easy integration of the data and hinder broader understanding of ecosystem dynamics. Ocean Observing Systems provide a specific example of multi-sensor systems observing several variables in different space - time regimes. This project integrates diverse space-time environmental sensor streams based on the conversion of their information content to a common higher-level abstraction: a space-time event data type. The space-time event data type normalizes across the diversity of observation level data to produce a common data type for exploration and analysis. Gulf of Maine Ocean Observing System (GOMOOS) …
Determining Patterns Of Abrupt Climate Change During The Last Glacial-Interglacial Transition (Lgit) In The Southern Hemisphere, Marcus J. Vandergoes, Ann Dieffenbacher-Krall
Determining Patterns Of Abrupt Climate Change During The Last Glacial-Interglacial Transition (Lgit) In The Southern Hemisphere, Marcus J. Vandergoes, Ann Dieffenbacher-Krall
University of Maine Office of Research Administration: Grant Reports
This proposal will fund the development of a continuous, isotopically-dated paleochironomid and pollen record of deglacial climate fluctuations from lake sediments located in climatically sensitive sites along the Southern Alps, New Zealand. Detailed investigations will be carried out for the Last Glacial-Interglacial Transition (LGIT) at Boundary Stream Tarn, Quagmire Tarn, and Kettlehole Bog to establish the sequence of deglacial climate events and to facilitate comparisons with other well-dated northern and southern records.
The primary scientific objectives of the project are to determine: 1) the pattern and magnitude of past climate change; 2) whether changes recorded show an in-phase or out-of-phase …

Collaborative Research: Centers For Ocean Science Education Excellence- Ocean In The Earth-Sun System, Lee Karp-Boss, Emmanuel S. Boss
University of Maine Office of Research Administration: Grant Reports
This award establishes a new Center for Ocean Science Education Excellence (COSEE) via awards to the Bigelow Laboratory for Ocean Sciences (0528706), the University of Maine (0528702), and the University of New Hampshire (0528686). The main goals of this thematic Center are to broaden understanding of the oceans in the context of the earth and solar systems and to help the COSEE network reach rural and inland audiences. The PIs will pioneer a system of interfaces, tools, and resources to reach underserved and underrepresented groups, and to bring ocean sciences to inland audiences by presenting it in the context of …
Physical Properties Of The Us Itase Firn And Ice Cores From South Pole To Taylor Dome, Debra A. Meese, Ian Baker
Physical Properties Of The Us Itase Firn And Ice Cores From South Pole To Taylor Dome, Debra A. Meese, Ian Baker
University of Maine Office of Research Administration: Grant Reports
This award supports a project for physical properties research on snow pits and firn/ice cores with specific objectives that include stratigraphic analysis including determination of accumulation rates, annual layers, depth hoar, ice and wind crusts and rates of grain growth with depth. Studies of firn densification rates and how these parameters relate to the meteorology and climatology over the last 200 years of snow accumulation in Antarctica will also be investigated. The project will also determine the seasonality of accumulation by co-registration of stratigraphy and chemistry and determination of chemical species at the grain boundaries, how these may change with …

U.S. Globec: Nwa Georges Bank - Processes Controlling Abundance Of Dominant Copepod Species On Georges Bank: Local Dynamics And Large-Scale Forcing, Jeffrey A. Runge
University of Maine Office of Research Administration: Grant Reports
A fundamental goal of Biological Oceanography is to understand how underlying biological-physical interactions determine abundance of marine organisms. For animal populations, it is well known that factors controlling survival during early life stages (i.e., recruitment) are strong determinants of adult population size, but understanding these processes has been difficult due to model and data limitations. Recent advances in numerical modeling, together with new 3D data sets, provide a unique opportunity to study the biological-physical processes controlling zooplankton population size. This project uses an existing state-of-the-art biological/physical numerical model (FVCOM) together with the recently processed large 3D data set from the …

U.S.-Globec: Nep Phase Iiib-Cgoa: A Synthesis Of Climate-Forced Variability On Mesoscale Structure In The Cgoa With Direct Comparisons To The Ccs, Andrew C. Thomas
University of Maine Office of Research Administration: Grant Reports
A variety of extreme climate events occurred during the period of US GLOBEC monitoring and process studies in the NEP (1997-2004). These provide an unprecedented opportunity to examine a range of climate variability experienced by the coastal Gulf of Alaska (CGOA). By relating these climate events to regional physical and biological observations, using multiple and diverse data sources (GLOBEC observations, historical data sets and reanalyses, satellites, models), we can determine how these events affect mesoscale ocean variability in the CGOA and its related target populations (the primary goal of the NEP program). We can then directly compare these responses to …
U.S.-Globec: Nwa Georges Bank: Effects Of Climate Variability On Calanus Dormancy Patterns And Population Dynamics In The Northwest Atlantic, Jeffrey A. Runge
U.S.-Globec: Nwa Georges Bank: Effects Of Climate Variability On Calanus Dormancy Patterns And Population Dynamics In The Northwest Atlantic, Jeffrey A. Runge
University of Maine Office of Research Administration: Grant Reports
Calanoid copepods are key organisms throughout the world's oceans, consuming primary and secondary production at high rates, and serving as prey for invertebrates, larval and small pelagic fish, seabirds, and marine mammals. Many of the most abundant copepods in temperate and high latitudes, including Calanus finmarchicus in the Northwest Atlantic, can spend part of their life cycle in dormancy, a state of suppressed development. During dormancy, copepods escape unproductive surface waters and reside in deep water for several months, after which they emerge and migrate to the surface, usually prior to the spring bloom. The timing and abundance of copepods …

Collaborative Proposal: Cascadia Slope Circulation Study, Mary Jane Perry
University of Maine Office of Research Administration: Grant Reports
Intellectual Merits:
This project will continue to observe and understand the physics and biology of the highly productive northeast Pacific boundary current region over the continental slope off Washington and Oregon - the Cascadia slope - with an autonomous, sustained presence. For over a year, Seagliders, long-range autonomous underwater vehicles, have been deployed to survey the temperature, salinity, dissolved, oxygen, chlorophyll fluorescence, and optical backscatter structure of the slope off. Washington. Seagliders have collected data on sections from the continental shelf edge offshore 220 km at fortnightly intervals, reporting back data after each dive, on deployments typically lasting 4-5 months. …
