Geologic framework, evolution, and sediment resources for restoration of the Louisiana Coastal Zone
Mark Kulp, Shea Penland, S. Jeffress Williams, Chris Jenkins, Jim Flocks, Jack Kindinger
2005, Journal of Coastal Research (44) 56-71
The Louisiana Coastal Zone along the north-central Gulf of Mexico represents one of America's most important coastal ecosystems in terms of natural resources, human infrastructure, and cultural heritage. This zone also has the highest rates of coastal erosion and wetland loss in the nation because of a complex combination of...
Preliminary assessment of recent deposition related to a crevasse splay on the Mississippi River delta: Implications for coastal restoration

2005, Gulf Coast Association of Geological Societies Transactions (55) 185-194
Historically, the Mississippi River has replenished sediment across the lower deltaic plain, abating land loss. However, flood-control structures along the river now restrict this natural process and divert sediment from the modern delta offshore to the shelf break, thereby removing it from the coastal system. Localized crevasse splays, however,...

Habitat and fish population in the deep-sea Oculina coral ecosystem of the western Atlantic
2005, Conference Paper, Benthic habitats and the effects of fishing: Proceedings of Symposium on Effects of Fishing Activities on Benthic Habitats--Linking Geology, Biology, Socioeconomics, and Management
In this paper, we describe results from mapping studies conducted in 2001 and improvements to reef fish populations that have occurred in the last few years. We find that less than 10% of the area contains intact Oculina coral thickets, which we continue to attribute primarily to trawling. In addition,...

2005, Eos, Transactions, American Geophysical Union (86) 537-540
There is renewed interest in studying the active and complex northeastern Caribbean plate boundary to better understand subduction zone processes and for earthquake and tsunami hazard assessments [e.g., ten Brink and Lin, 2004; ten Brink et al., 2004; Grindlay et al., 2005]. To study the active tectonics of this plate boundary, the GEOPRICO-DO...
Comparison of cytochrome P450 1A induction in blood and liver cells of sea otters
Brenda E. Ballachey, Paul W. Snyder, Tamara Kondratyuk
2005, Report
Sea otters in oiled areas of western PWS had elevated levels of cytochrome P450 1A (CYP1A), a biomarker of hydrocarbon exposure, measured in blood samples collected from otters in 1996- 98. In summer 2001, as part of project 01423, we have proposed to resample CYP1A in blood from sea otters...

2005, Scientific Investigations Report 2005-5241
Lake Houston is a major source of public water supply and recreational resource for the Houston metropolitan area, Texas. Water-quality issues of potential concern for the lake have included nutrient enrichment (orthophosphorus, total phosphorus, nitrite plus nitrate) and aquatic life use (dissolved oxygen). The , in cooperation with the City...

Toward predicting barrier island vulnerability: Simple models for dune erosion
Laura A. Fauver, Peter A. Advised by Howard
2005, Thesis
The objective of this study is to quantify the accuracy of two engineering models for dune erosion (SBEACH and EDUNE), and to determine which of the two models is best suited for predicting barrier island vulnerability due to extreme storm events. The first model, SBEACH, computes sediment transport using empirically...
Scanning electron microscope studies of some early Miocene diatoms from the equatorial Pacific Ocean with descriptions of two new species, Actinocyclus jouseae Barron and Actinocyclus nigriniae Barron
John A. Barron
2005, Proceedings of the California Academy of Sciences (1907) (56) 27-37
Scanning electron microscope (SEM) and light microscope (LM) studies are used to propose and describe two new species, Actinocyclus jouseae Barron, sp. nov. and Actinocyclus nigriniae Barron, sp. nov. from lower Miocene sediments from equatorial Pacific ODP Site 1219. Parallel SEM and LM studies reveal that Thalassiosira bukryi Barron should be transferred to Azpeitia...

2005, Report
Agency land-use must be efficiently and cost-effectively monitored to assess conditions and trends in ecosystem processes and natural resources relevant to mission requirements and legal mandates. Ecological Indicators represent important land management tools for tracking ecological changes and preventing irreversible environmental damage in disturbed landscapes. The overall objective of the...

The passing of seasons, as gauged by annual events or phenophases in organisms' life cycles, is arguably one of the most pervasive environmental variations on Earth. Shifts in seasonal timing, or phenology, are observed in flowering and other stages of plant development, animal migration and reproduction, hibernation, and the seasonal...

Guidelines 13 and 14—Prediction uncertainty
Mary C. Hill, Claire R. Tiedeman
2005, Book chapter, Effective Groundwater Model Calibration: With Analysis of Data, Sensitivities, Predictions, and Uncertainty
An advantage of using optimization for model development and calibration is that optimization provides methods for evaluating and quantifying prediction uncertainty. Both deterministic and statistical methods can be used. Guideline 13 discusses using regression and post-audits, which we classify as deterministic methods. Guideline 14 discusses inferential statistics and Monte Carlo...
