Description
Despite the wealth of folk music traditions in Portugal and the importance of the clarinet in the music of bandas filarmonicas, it is uncommon to find works featuring the clarinet using Portuguese folk music elements. In the interest of expanding this type of repertoire, three new works were commissioned from three different composers. The resulting works are Seres Imaginarios 3 by Luis Cardoso; Delirio Barroco by Tiago Derrica; and Memória by Pedro Faria Gomes. In an effort to submit these new works for inclusion into mainstream performance literature, the author has recorded these works on compact disc. This document includes interview transcripts with each composer, providing first-person discussion of each composition, as well as detailed biographical information on each composer. To provide context, the author has included a brief discussion on Portuguese folk music, and in particular, the role that the clarinet plays in Portuguese folk music culture.

Description
The phytoplankton communities in the open oceans are dominated by picophytoplankton (0.7-2µm) and nanophytoplankton (3-5µm). Studying the community dynamics of these phytoplankton is important to learn about their role in the carbon cycle and food web of the oceans. Dilution experiments were used, along with microscopy and molecular techniques, to determine abundance, biomass and phytoplankton growth and grazing rates in the oligotrophic Sargasso Sea (western North Atlantic subtropical gyre) around the Bermuda Atlantic Time Series Station (BATS) in the summer of 2012. With low biomass and chlorophyll a, the Sargasso Sea appears to be unproductive at first glance, but I found that pico- and nanophytoplankton have high instantaneous growth rates that are balanced by the high grazing rates of microzooplankton.
Mesoscale eddies are important features in the Sargasso Sea that can increase or decrease the available nutrients in the euphotic zone. Two different mesoscale eddies were sampled: an anti-cyclonic eddy and the BATS station which was located at the edge of a cyclonic eddy. The results indicated that BATS had overall higher instantaneous growth (µ between 0.1 d-1 and 3.7 d-1) and grazing rates on pico- and nanophytoplankton, as well as diatoms, compared to the anti-cyclonic eddy (µ between 0.2 d-1 and 3 d-1). I also determined taxon-specific rates using quantitative polymerase chain reaction (qPCR) for the order Mamiellales, one of the smallest representatives of the abundant prasinophytes. This method yielded surprisingly high growth (9.7 d-1 ) and grazing rates (-8.2 d-1) at 80m for BATS. The euphotic zone (~100m) integrated biomass of all phytoplankton did not vary significantly between BATS (379 mg C m-2) and the anti-cyclonic eddy (408 mg C m-2) and the net growth rates at both locations were very close to zero for most of the groups. Although the biomass and net growth rates did not vary greatly between the two locations, the high instantaneous growth and grazing rates of pico- and nano-eukaryotic phytoplankton indicate an increase in the rate of the marine microbial food web, or microbial loop, compared to the anti-cyclonic eddy. This could have been due to the input of new nutrients in the edge of the cyclonic eddy at BATS. Thus, my study suggests that mesoscale variability is of considerable importance for the dynamics of the phytoplankton community and their role in the microbial loop. Much can be learned when using DNA based taxon-specific rates, especially to understand the relative importance and contribution of specific taxa.
More taxon-specific molecular studies will have to be carried out to quantify specific rates of more phytoplankton groups, which will supply a more complete knowledge of phytoplankton community dynamics in the Sargasso Sea. This will increase our understanding of the role of specific groups to the biological carbon dynamics in the euphotic zone into the deep ocean.

Description
This project includes a recording and performance guide for three newly commissioned pieces for the clarinet. The first piece, shimmer, was written by Grant Jahn and is for B-flat clarinet and electronics. The second piece, Paragon, is for B-flat clarinet and piano and was composed by Dr. Theresa Martin. The third and final piece, Duality in the Eye of a Bovine, was written by Kurt Mehlenbacher and is for B-flat clarinet, bass clarinet, and piano. In addition to the performance guide, this document also includes background information and program notes for the compositions, as well as composer biographical information, a list of other works featuring the clarinet by each composer, and transcripts of composer and performer interviews. This document is accompanied by a recording of the three pieces.

Description
The primary objective of this research project is to expand the clarinet repertoire with the addition of four new pieces. Each of these new pieces use contemporary clarinet techniques, including electronics, prerecorded sounds, multiphonics, circular breathing, multiple articulation, demi-clarinet, and the clari-flute. The repertoire composed includes Grant Jahn’s Duo for Two Clarinets, Reggie Berg’s Funkalicious for Clarinet and Piano, Rusty Banks’ Star Juice for Clarinet and Fixed Media, and Chris Malloy’s A Celestial Breath for Clarinet and Electronics. In addition to the musical commissions, this project also includes interviews with the composers indicating how they wrote these works and what their influences were, along with any information pertinent to the performer, professional recordings of each piece, as well as performance notes and suggestions.

Description
Phytoplankton comprise the base of the marine food web, and, along with heterotrophic protists, they are key players in the biological pump that transports carbon from the surface to the deep ocean. In the world's subtropical oligotrophic gyres, plankton communities exhibit strong seasonality. Winter storms vent deep water into the euphotic zone, triggering a surge in primary productivity in the form of a spring phytoplankton bloom. Although the hydrographic trends of this "boom and bust" cycle have been well studied for decades, community composition and its seasonal and annual variability remains an integral subject of research. It is hypothesized here that proportions of different phytoplankton and protistan taxa vary dramatically between seasons and years, and that picoplankton represent an important component of this community and contributor to carbon in the surface ocean. Monthly samples from the Bermuda Atlantic Time-series Study (BATS) site were analyzed by epifluorescence microscopy, which permits classification by morphology, size, and trophic type. Epifluorescence counts were supplemented with flow cytometric quantification of Synechococcus, Prochlorococcus, and autotrophic pico- and nanoeukaryotes. Results from this study indicate Synechococcus and Prochlorococcus, prymnesiophytes, and hetero- and mixotrophic nano- and dinoflagellates were the major players in the BATS region plankton community. Ciliates, cryptophytes, diatoms, unidentified phototrophs, and other taxa represented rarer groups. Both flow cytometry and epifluorescence microscopy revealed Synechococcus to be most prevalent during the spring bloom. Prymnesiophytes likewise displayed distinct seasonality, with the highest concentrations again being noted during the bloom. Heterotrophic nano- and dinoflagellates, however, were most common in fall and winter. Mixotrophic dinoflagellates, while less abundant than their heterotrophic counterparts, displayed similar seasonality. A key finding of this study was the interannual variability revealed between the two years. While most taxa were more abundant in the first year, prymnesiophytes experienced much greater abundance in the second year bloom. Analyses of integrated carbon revealed further stark contrasts between the two years, both in terms of total carbon and the contributions of different groups. Total integrated carbon varied widely in the first study year but displayed less fluctuation after June 2009, and values were noticeably reduced in the second year.
