Assessing Nature’s Role in Resilience (Video)

A new video describing an ESLR-funded project was released by project partners this week. Maryland has an abundance of habitats that can help mitigate the effects of sea level rise, ...

Advanced Flood Modeling Study Predicts Impacts and...

A study, funded in part by NOAA, developed an integrated and transferable framework for evaluating the physical, economic, and demographic impacts and benefits of "gray", i.e. seawalls, bulkheads, and dikes, ...

New Research Improves Flood Modeling for Large Urb...

Coastal managers need accurate flood forecasts to protect communities from inundation. New research, funded in part by NCCOS, improves how levees are represented in flood models used to identify vulnerabilities ...

Los Angeles Flood Risk - distribution of predominant race/ethnicity (left) and flood depth (right). Six weeks after the scientific study Large and inequitable flood risks in Los Angeles, California was ...

Atmospheric River Storms Threaten Communities and ...

Atmospheric rivers — also known as "rivers in the sky" — are long, narrow bands of concentrated water vapor that can produce high winds and massive amounts of snow and ...

Resilient Coastal Cities Need to Know the Five W’s...

There is growing evidence that flood risks in the United States have historically been underestimated, and will disproportionately impact individuals within low-wealth and marginalized communities. New research offers the Los ...

Data & Publications

A Scenario and Forecast Model for Gulf of Mexico Hypoxic Area and Volume

For almost three decades, the relative size of the hypoxic region on the Louisiana-Texas continental shelf has drawn scientific and policy attention. During that time, both simple and complex models have been used to explore hypoxia dynamics and to provide ...

Carbon Dynamics on the Louisiana Continental Shelf and Cross-Shelf Feeding of Hypoxia

Large-scale hypoxia regularly develops during the summer on the Louisiana continental shelf. Traditionally, hypoxia has been linked to the vast winter and spring nutrient inputs from the Mississippi River and its distributary, the Atchafalaya River. However, recent studies indicate that ...

Changes in Mississippi River Water Quality this Century: Implications for Coastal Food Webs

In this article, we quantify some important changes in water quality for the Lower Mississippi River for this century and then suggest their causes and possible impact ...

Coastal eutrophication near the Mississippi river delta

Changes in delivery of river-borne nutrients such as dissolved phosphate, nitrate and silicate, owing to land-use changes and anthropogenic emissions, are known to result in eutrophication1— enhanced phytoplankton blooms—and more severe hypoxic events2–1 in many enclosed bays and seas. Although ...

Dynamic responses and implications to coastal wetlands and the surrounding regions under sea level rise

Two distinct microtidal estuarine systems were assessed to advance the understanding of the coastal dynamics of sea level rise in salt marshes. A coupled hydrodynamic-marsh model (Hydro-MEM) was applied to both a marine-dominated (Grand Bay, Mississippi) and a mixed fluvial/marine ...

Dynamics and distribution of natural and human-caused coastal hypoxia

Water masses can become undersaturated with oxygen when natural processes alone or in combination with anthropogenic processes produce enough organic carbon that is aerobically decomposed faster than the rate of oxygen re-aeration. The dominant natural processes usually involved are photosynthetic ...

Eutrophication-Driven Deoxygenation in the Coastal Ocean

Human activities, especially increased nutrient loads that set in motion a cascading chain of events related to eutrophication, accelerate development of hypoxia (lower oxygen concentration) in many areas of the world’s coastal ocean. Climate changes and extreme weather events may ...

Gulf of Mexico Hypoxia: Exploring Increasing Sensitivity to Nitrogen Loads

Hypoxia is a critical issue in the Gulf of Mexico that has challenged management efforts in recent years by an increase in hypoxia sensitivity to nitrogen loads. Several mechanisms have been proposed to explain the recent increase in sensitivity. Two ...

Hydrographic and chemical water parameters collected by CTD and other instruments from the Pelican and the Tommy Munro in coastal waters of Louisiana from 1994-07-24 to 1997-07-29 (NCEI Accession 0164298)

Hydrographic and chemical data were collected for a week in late July between 1994-1997 in order to survey the coastal hypoxia on Louisiana continental shelf. Nutrient, pigment, suspended sediment and station information data were also acquired. Data files provided in ...

Louisiana Hypoxia Survey 2009: Biological, chemical, and physical data collected off the coast of Louisiana as part of the Hypoxia Studies in the Northern Gulf of Mexico project in 2009 (NODC Accession 0099531)

CTD data were taken during the 2009 surveys of the Louisiana continental shelf. Hydrographic data were obtained with the LUMCON SeaBird 911+ CTD system and a YSI 6820. Nutrient, pigment, suspended sediment, surface salinity, secchi depth, and station information data ...
