Quantifying Seasonal Air-Sea Gas Exchange Processes Using Noble Gas Time-Series: A Design Experiment, Rachel H. R. Stanley, William J. Jenkins, Scott C. Doney

Journal of Marine Research

A multi-year time-series of measurements of five noble gases (He, Ne, Ar, Kr, and Xe) at a subtropical ocean location may allow quantification of air-sea gas exchange parameters with tighter constraints than is currently available by other methods. We have demonstrated this using a one-dimensional upper ocean model forced by 6-hourly NCEP reanalysis winds and heat flux for the Sargasso Sea near Bermuda. We performed ensemble model runs to characterize the response of the modeled noble gas saturation anomalies to a range of air-sea gas exchange parameters. We then used inverse calculations to quantify the sensitivity of the parameters to …

Synoptic Lagrangian Maps: Application To Surface Transport In Monterey Bay, B. L. Lipphardt Jr., D. Small, A. D. Kirwan Jr., S. Wiggins, K. Ide, C. E. Grosch, J. D. Paduan

Journal of Marine Research

Here we report on an effort to describe in detail the evolution of surface water particles in Monterey Bay from the time they first enter until the time they leave. The data used for this study are objective mappings from hourly surface currents obtained from high frequency (HF) radar measurements in Monterey Bay for the period 2 June through 4 August 1999. The basic concept is simple: compute the origin and fate of a large number of particles for every hour during the analysis period. However, analyzing and displaying the enormous amount of computed trajectory information required a new data …

Beam Attenuation And Chlorophyll Concentration As Alternative Optical Indices Of Phytoplankton Biomass, Michael J. Behrenfeld, Emmanual Boss

Journal of Marine Research

Chlorophyll has long functioned as the prominent field metric for phytoplankton biomass, but its variability can be strongly influenced by (even dominated by) physiological shifts in intracellular pigmentation in response to changing growth conditions (light, nutrients, temperature). The particulate beam attenuation coefficient (c_p) may offer an alternative optical measure of phytoplankton biomass that is readily assessed in situ and relatively insensitive to changes in intracellular pigment content. Unlike chlorophyll, however, c_p is not uniquely associated with phytoplankton and varies as well with changes in inorganic, detrital, and heterotrophic particles. In open ocean environments, particles in the …

Does The Marine Biosphere Mix The Ocean?, W. K. Dewar, R. J. Bingham, R. L. Iverson, D. P. Nowacek, L. C. St. Laurent, P. H. Wiebe

Journal of Marine Research

Ocean mixing is thought to control the climatically important oceanic overturning circulation. Here we argue the marine biosphere, by a mechanism like the bioturbation occurring in marine sediments, mixes the oceans as effectively as the winds and tides. This statement is derived ultimately from an estimated 62.7 TeraWatts of chemical power provided to the marine environment in net primary production. Various approaches argue something like 1% (.63 TeraWatts) of this power is invested in aphotic ocean mechanical energy, a rate comparable to wind and tidal inputs.

Acoustic Observations Of Vertical And Horizontal Swimming Velocities Of A Diel Migrator, C. Smyth, A. E. Hay, P. S. Hill, D. Schillinger

Journal of Marine Research

A strong sound scattering layer which underwent diel vertical migration was observed over 176 days using a bottom-mounted 600 kHz ADCP at a depth of approximately 285 m on the upper continental slope. Average observed descent times of the scatterers were within 12 minutes of sunrise and average ascent times were within 13 minutes of sunset. Average ascent speeds progressively increased away from the bed and approached 6 cm/s. Average descent speeds similarly reached a maximum of ∼6 cm/s. Horizontal velocities of the scatterers during vertical migration were found to be smaller than ambient velocities (by up to 3 cm/s), …

Estimation Of Mixed-Layer Depth From Surface Parameters, D. Swain, M. M. Ali, R. A. Weller

Journal of Marine Research

Mixed layer depth (MLD) is an important oceanographic parameter. However, the lack of direct observations of MLD hampers both specification and investigation of its spatial and temporal variability. An important alternative to direct observation would be the ability to estimate MLD from surface parameters easily available from satellites. In this study, we demonstrate estimation of MLD using Artificial Neural Network methods and surface meteorology from a surface mooring in the Arabian Sea. The estimated MLD had a root mean square error of 7.36 m and a coefficient of determination (R²) of 0.94. About 67% (91%) of the …

Books/Book chapters

In the United States, approximately 17,000 people per year are diagnosed with brain tumors, the leading cause of death from cancers in children ages 1-15 year (1,2). Gliomas are the most prevalent type of brain tumors in adults, affecting 3.2/100,000 persons/yr in the United States (www.CBTRUS.org). In spite of advances in surgery, chemotherapy, and radiotherapy, the mean survival time of patients post-diagnosis remains approximately 9-12 months.

Swarm Intelligence: Theoretical Proof That Empirical Techniques Are Optimal, Dmitry Iourinskiy, Scott A. Starks, Vladik Kreinovich, Stephen F. Smith

Departmental Technical Reports (CS)

A natural way to distribute tasks between autonomous agents is to use swarm intelligence techniques, which simulate the way social insects (such as wasps) distribute tasks between themselves. In this paper, we theoretically prove that the corresponding successful biologically inspired formulas are indeed statistically optimal (in some reasonable sense).

The Continuing War On Academic Freedom And Tenure: Will They Survive?, Keith T. Hardeman

Iowa Journal of Communication

Since knowledge is not a product that can be shaped and manufactured to meet the spiritual or political needs of various customers, academic freedom must exist to protect faculty in the ultimate search for and dissemination of truth. Just as freedom of speech is safeguarded by the Constitution, academic freedom must be defended by tenure. This article explains the need for tenure by addressing its more popular fallacies and some of the current attempts to erode its strength.

Corporate Perspectives On The Vedic Meditative Practice Upasana, P. S. Rao, P. N. Murthy

International Journal of Transpersonal Studies

A business corporation capable of evolving, termed a learning corporation, has a conscious quality. It is the systemic version of a rigid structure-preserving corporation that would be expected eventually to run into problems and end up as a failure. The conscious corporation analogy can be used to simulate the sequence of processes that occur during Upasana, a Vedic technique of meditation. In this essay, it will be argued that (1) the Vedic view of consciousness is parallel to the postulate that successful business corporations have a conscious quality, and (2) if the Upasana process sequence is considered as a competence …

Spring Thaw And Its Effect On Terrestrial Vegetation Productivity In The Western Arctic Observed From Satellite Microwave And Optical Remote Sensing, John S. Kimball, K. C. Mcdonald, M. Zhao

Numerical Terradynamic Simulation Group Publications

Global satellite remote sensing records show evidence of recent vegetation greening and an advancing growing season at high latitudes. Satellite remote sensing–derived measures of photosynthetic leaf area index (LAI) and vegetation gross and net primary productivity (GPP and NPP) from the NOAA Advanced Very High Resolution Radiometer (AVHRR) Pathfinder record are utilized to assess annual variability in vegetation productivity for Alaska and northwest Canada in association with the Western Arctic Linkage Experiment (WALE). These results are compared with satellite microwave remote sensing measurements of springtime thaw from the Special Sensor Microwave Imager (SSM/I). The SSM/I-derived timing of the primary springtime …

Invisible Chains: Psychological Coercion Of Human Trafficking Victims, Elizabeth Hopper, Jose Hidalgo

Intercultural Human Rights Law Review

The terror that grips a victim of abuse can be the same whether physical violence or psychological force is used. Rashi was a victim of modem-day slavery for over ten years. She was brought to the United States as a domestic servant and was forced to work from morning to night, was not paid, and was made to sleep on a mat on the floor. She was forced to beg for her meager portions of food and suffered from untreated tuberculosis because she was not allowed to seek medical care. Rashi had no contact with the outside world because her …

Accepting Exceptions?: A Comparative Approach To Experimental Use In U.S. And German Patent Law, Peter Ruess

Marquette Intellectual Property Law Review

Experimental use is a keystone of research and innovation for some and obstacle in using a patent for others. In a genuine international field such as patent law, monitoring recent developments is best done in a comparative way. Particularly, the decision Merck v. Integra of the US Supreme Court and the new EU law, give reason to explore this field in more detail.

Of The Inequals Of The Uruguay Round, Srividhya Ragavan, Srividhya Ragavan

Marquette Intellectual Property Law Review

Ten years ago, the TRIPs Agreement set a distinct tone in international law by requiring Members to prioritize international trade obligations as a means to achieve national goals. Within the next five years, the AIDS crisis highlighted that compromising pressing national responsibilities-like a looming public health crisis-to fulfill international obligations may, in fact, detrimentally affect international trade. Meanwhile, access to medication continues to be an unresolved issue even as we celebrate the tenth anniversary of TRIPs and the end of the transitional period. This Article suggests that the success of TRIPs depends on its ability to address national responsibilities that …

Growth And Survivorship Of Scleractinian Coral Transplants And The Effectiveness Of Plugging Core Holes In Transplant Donor Colonies, Elizabeth Glynn Fahy, Richard E. Dodge, Daniel P. Fahy, T. Patrick Quinn, David S. Gilliam, Richard E. Spieler

Marine & Environmental Sciences Faculty Proceedings, Presentations, Speeches, Lectures

Replicate scleractinian coral transplants were obtained from the species Meandrina meandrites and Montastrea cavernosa on a natural reef, off Dania Beach, Florida, using a hydraulic drill fitted with a 4 in. (~10 cm) core barrel. The transplants were fixed to Reef Ball™ substrates using an adhesive marine epoxy. Drill holes in the donor corals (core holes) were filled with concrete plugs. Control corals, of comparable size to both donor colonies and transplant corals, were monitored for comparison. Transplant corals, donor corals, and controls on the natural reef were monitored for growth and survivorship. Core holes were monitored for tissue regrowth …

Spatial Patterns In Arabian Gulf Coral Assemblages (Jebel Ali, Dubai, U.A.E.) In Response To Temperature-Forcing, Bernhard Riegl, Samuel J. Purkis, Kevin E. Kohler, Richard E. Dodge

Marine & Environmental Sciences Faculty Proceedings, Presentations, Speeches, Lectures

We evaluated spatial and temporal patterns using maps from Ikonos satellite imagery in combination with 8 years of line transects and photosquares and the HadISST1 sea-surface temperature data set to explain why coral assemblages in the southern Arabian Gulf (Dubai) are impoverished and mostly do not build framework reefs. Analysis of archive sea surface temperature (SST) data confirms that the area is subjected to recurrent temperature anomalies. Frequencies of anomalies might suggest at least a partial link to the El Niño Southern Oscillation possibly via the Indian Ocean Zonal Mode. The dominant driver of local temperature was oscillations in the …

An Experimental Histopathological Rating Scale Of Sedimentation Stress In The Caribbean Coral Montastraea Cavernosa, Bernardo Vargas-Ángel, Bernhard Riegl, David S. Gilliam, Richard E. Dodge

Marine & Environmental Sciences Faculty Proceedings, Presentations, Speeches, Lectures

Colonies of Montastraea cavernosa were exposed to daily applications of approx. 200–225 mg cm– 2 sediments, during a four-week period, in order to investigate coral responses to increased sedimentation. Effects were assessed based on the histopathological condition of specimen tissues. Mild stress responses were noted as early as week one, including tissue swelling and polyp retraction, as well as changes in size and appearance of mucous secretory cells. As stress progressed, further inflammation of the mucous secretory cells was observed. Severe effects were observed in weeks 3 and 4, including atrophy of the outer epidermis, increased granularity and debris in …

Tires: Unstable Materials For Artificial Reef Construction, Robin L. Sherman, Richard E. Spieler

Marine & Environmental Sciences Faculty Proceedings, Presentations, Speeches, Lectures

Artificial reefs of varied materials have been deployed worldwide to acquire large and diverse fish assemblages for both commercial and sport fishers, and SCUBA divers. Beginning in 1967, environmental resource managers and local fishers initiated a project to build an artificial reef using banded, but unballasted, waste automobile and truck tires offshore Broward County, Florida, USA. Estimates of the number of tires placed offshore range between 1,000,000– 2,000,000. Since deployment, storm events and ocean currents have caused the bands to give way and the break-up of the reef. Over the years, many tires have washed ashore onto recreational beach areas. …

Visual_Hea: Habitat Equivalency Analysis Software To Calculate Compensatory Restoration Following Natural Resource Injury, Kevin E. Kohler, Richard E. Dodge

Marine & Environmental Sciences Faculty Proceedings, Presentations, Speeches, Lectures

Habitat Equivalency Analysis (HEA) is a means to determine the amount of compensatory restoration required to provide services that are equivalent to the interim loss of natural resource services following an injury. HEA includes a discounting procedure to account for asset valuation in that the total asset value is equal to the discounted value of the future stream of all services from the natural resource or the compensatory resource. Discounting is used to include the relative valuation of loss and gain of ecological services of the resources over time. Visual_HEA is a computer program developed to calculate the amount of …

Coral Of Opportunity Survivorship And The Use Of Coral Nurseries In Coral Reef Restoration, Jamie A. Monty, David S. Gilliam, Kenneth Banks, David K. Stout, Richard E. Dodge

Marine & Environmental Sciences Faculty Proceedings, Presentations, Speeches, Lectures

Coral reef damage is unfortunately becoming a common occurrence off southeast Florida, U.S.A. Reattachment of the dislodged scleractinian corals usually initiates damage site restoration. Because mortality of dislodged colonies is typically high and natural recovery in southeast Florida is typically slow, transplantation of additional scleractinian corals into a damaged area has been used to accelerate reef recovery. Donor colonies available for transplantation have been grown in situ, grown in laboratories, and taken from nondamaged reef areas. An alternative source of donor colonies for transplantation into damaged sites is “corals of opportunity,” which we define as scleractinian corals that have been …
