Hemispheric Comparison Of Cirrus Cloud Evolution Using In Situ Measurements In Hiaper Pole-To-Pole Observations, 2014 National Center for Atmospheric Research
Hemispheric Comparison Of Cirrus Cloud Evolution Using In Situ Measurements In Hiaper Pole-To-Pole Observations, Minghui Diao, Mark Zondlo, Andrew Heymsfield, Stuart Beaton
Faculty Publications, Meteorology and Climate Science
The radiative forcing of cirrus clouds is highly sensitive to their microphysical properties as well as their evolution. However, there are very limited observations and analyses on the cirrus cloud formation and evolution with both microscale resolution and global scale coverage. The lack of such observations limits the overall comparison of cirrus cloud evolution between the two hemispheres. In fact, the previous hemispheric comparisons of cirrus cloud microphysics using in situ observations were only based on the sampling over two locations at 55°N and 55°S (Ovarlez et al., 2002; Gayet et al., 2004). Here we use a more comprehensive aircraft-based …

Timing Of Svalbard/Barents Sea Ice Sheet Decay During The Last Glacial Termination, 2014 University of South Florida
Timing Of Svalbard/Barents Sea Ice Sheet Decay During The Last Glacial Termination, Tasha Snow
USF Tampa Graduate Theses and Dissertations
The Arctic and North Atlantic underwent significant climactic changes since the Last Glacial Maximum (25,000 years before present (1950 AD); ka BP), but offsets in the timing of events between the two regions are poorly constrained due to age model uncertainties that arise from changing radiocarbon reservoir ages. Here, we use a relatively high-resolution, multi-proxy stable isotope and sedimentologic dataset from Eastern Fram Strait (ODP Leg 162 Site 986) marine sediments to constrain the timing of Svalbard/Barents Sea Ice Sheet decay and infer deglacial reservoir ages over the last 30 ka. We use magnetic susceptibility, inorganic and organic carbon, foraminiferal …

Future changes in the stratospheric circulation could have an important impact on northern winter tropospheric climate change, given that sea level pressure (SLP) responds not only to tropospheric circulation variations but also to vertically coherent variations in troposphere-stratosphere circulation. Here we assess northern winter stratospheric change and its potential to influence surface climate change in the Coupled Model Intercomparison Project-Phase 5 (CMIP5) multimodel ensemble. In the stratosphere at high latitudes, an easterly change in zonally averaged zonal wind is found for the majority of the CMIP5 models, under the Representative Concentration Pathway 8.5 scenario. Comparable results are also found in …
Environmental Variability And Biodiversity Of Megabenthos On The Hebrides Terrace Seamount (Northeast Atlantic), 2014 Heriot-Watt University - Edinburgh, United Kingdom
Environmental Variability And Biodiversity Of Megabenthos On The Hebrides Terrace Seamount (Northeast Atlantic), Lea-Anne Henry, Johanne Vad, Helen S. Findlay, Javier Murillo, Rosanna Milligan, J. Murray Roberts
Marine & Environmental Sciences Faculty Articles
We present the first remotely operated vehicle investigation of megabenthic communities (1004–1695 m water depth) on the Hebrides Terrace Seamount (Northeast Atlantic). Conductivity-temperature-depth casts showed rapid light attenuation below the summit and an oceanographic regime on the flanks consistent with an internal tide, and high short-term variability in water temperature, salinity, light attenuation, aragonite and oxygen down to 1500 m deep. Minor changes in species composition (3–14%) were explained by changes in depth, substratum and oceanographic stability, whereas environmental variability explained substantially more variation in species richness (40–56%). Two peaks in species richness occurred, the first at 1300–1400 m where …
Understanding Copepod Life-History And Diversity Using A Next-Generation Zooplankton Model, 2014 Principal Investigator; University of Maine, Orono
Understanding Copepod Life-History And Diversity Using A Next-Generation Zooplankton Model, Andrew J. Pershing, Frederic Maps, Nicholas R. Record
University of Maine Office of Research Administration: Grant Reports
The main goal of our project is to understand the patterns of diversity and biogeography in marine copepods. To achieve this goal, we developed a unique modeling framework to simulate the trade-offs between growth, development, and fecundity in marine copepods.
We developed a new approach to modeling growth and development in metazoans. We applied this approach to marine copepods, and used it to understand relationships between copepod body size and temperature, copepod biodiversity patterns, and copepod biogeography. This project also provided support for experiments to look at how copepod body size impacts the particle size spectrum.
We used our model …

Understanding Copepod Life-History And Diversity Using A Next-Generation Zooplankton Model, Andrew J. Pershing, Frederic Maps, Nicholas Record
University of Maine Office of Research Administration: Grant Reports
Evolution has shaped the physiology, life history, and behavior of a species to the physical conditions and to the communities of predators and prey within its range. Within a community, the number of species is determined by both physical properties such as temperature and biological properties like the magnitude and timing of primary productivity, and ecological interactions such as predation. Despite well-known correlations between diversity and properties such as temperature, the mechanisms that drive these correlations are not well-described, especially in the oceans. The investigators will conduct a model-based investigation of diversity patterns in marine ecosystems, focusing on calanoid copepods. …

Aerosol Association With Severe Weather In The Great Plains, 2014 University of Nebraska-Lincoln
Aerosol Association With Severe Weather In The Great Plains, Gabriel A. Lojero
Department of Earth and Atmospheric Sciences: Dissertations, Theses, and Student Research
Aerosols particles may serve as cloud condensation nuclei (CCN) and therefore play an important role in modulating cloud microphysics, to the point where convective storm intensity may be altered. The purpose of this study is to determine the impacts of biomass burning aerosols on convective storms over the Great Plains, especially the southern Great Plains, and to show synoptic regimes characterizing differing aerosol concentrations. A new technique to identify days with a high concentration of biomass burning aerosols was developed by using organic carbon, potassium, zinc, and bromine as the predominant tracers. An eleven-year climatology (2002-2012) for the biomass burning …

The Saco River Plume: A Discussion Of The Near-Field Dynamics, 2014 University of New England
The Saco River Plume: A Discussion Of The Near-Field Dynamics, Barbara A. Fortier
All Theses And Dissertations
This study focused on the freshwater discharge plume from the Saco River in southwestern Maine to determine the mechanisms responsible for the largest impacts on the near-field dynamics in this region. We examined the forcing factors that tended to increase the plume's spatial extent upshelf of the river mouth. Salinity, temperature, and density data were collected during cruises from May through November 2010 and by two surface moorings deployed upshelf of the Saco River mouth. We found a distinct variation in the latitude of the upshelf boundary of the plume during and after periods of high discharge. Furthermore, we found …
Biophysical Interactions In The Straits Of Florida: Turbulent Mixing Due To Diel Vertical Migrations Of Zooplankton, 2014 Nova Southeastern University
Biophysical Interactions In The Straits Of Florida: Turbulent Mixing Due To Diel Vertical Migrations Of Zooplankton, Cayla Whitney Dean
HCNSO Student Theses and Dissertations
Diel vertical migrations (DVM) comprise the largest animal migration on the planet and are a phenomenon present in all bodies of water on Earth. A strong sound scattering layer undergoing DVM was observed in the Straits of Florida via a bottom-mounted Acoustic Doppler current profiler (ADCP) Workhorse Longranger 75 kHz (Teledyne RD Instruments) located at the 244 m isobath. ADCP average backscatter showed a clear periodicity corresponding with sunrise and sunset times indicating the presence of a nocturnal DVM. Analysis of the ADCP backscatter data indicated zooplankton swimming velocities were faster during sunrise than sunset times. In several cases the …
A Review Of Bottlenose Dolphin (Tursiops Truncatus) Vocalizations And An Investigation Into The Existence Of Signature Whistles In A Captive Dolphin Population, 2014 Nova Southeastern University
A Review Of Bottlenose Dolphin (Tursiops Truncatus) Vocalizations And An Investigation Into The Existence Of Signature Whistles In A Captive Dolphin Population, Gillian Reily
HCNSO Student Capstones
Individual recognition of conspecifics is important for various reasons in both terrestrial and marine dwelling species and is carried out through a variety of modes including visual, chemical and auditory cues. The ability to recognize individuals acoustically is often carried out through the use of signature vocalizations. The production and use of signature whistles within bottlenose dolphins has been extensively tested since their existence was first suggested almost 50 years ago. From the research, two primary hypotheses have emerged: the signature whistle hypothesis and the whistle repertoire hypothesis. This work discusses the various acoustical means of individual recognition found within …

An ensemble approach is used to examine the sensitivity of smoke loading and smoke direct radiative effect in the atmosphere to uncertainties in smoke emission estimates. Seven different fire emission inventories are applied independently to WRF-Chem model (v3.5) with the same model configuration (excluding dust and other emission sources) over the northern sub-Saharan African (NSSA) biomass-burning region. Results for November and February 2010 are analyzed, respectively representing the start and end of the biomass burning season in the study region. For February 2010, estimates of total smoke emission vary by a factor of 12, but only differences by factors of …

Marine Sciences Faculty Publications
Background: Satellite-based oceanographic data products are a valuable source of information on potential resource availability for marine species. Satellite oceanography data may be particularly useful in biotelemetry studies on marine species that feed at low trophic levels, such as zooplanktivorous whales, sharks, and rays. The basking shark, Cetorhinus maximus, is a well-documented zooplanktivore in the western North Atlantic, yet little is known of its movements and spatial ecology in this region. A combination of satellite tag technologies were used to describe basking shark movements with respect to concurrent satellite-observed oceanographic conditions in order to test for selection of these …
