Sea level to rise about three feet by 2100
Research geologists, Erika Lentz and Rob Thieler, discuss sea-level rise as one of the most certain outcomes of climate change: as the climate warms, land-based ice melts into the ocean, and a warmer ocean expands in volume.
Mendenhall Postdoctoral Research Fellow Joins Hurricane Sandy Estuarine Physical Response Project
In March 2015, Dan Nowacki joined the U.S. Geological Survey (USGS) Woods Hole Coastal and Marine Science Center in Woods Hole, Massachusetts. Dan is a Mendenhall Research Fellow working primarily with USGS research oceanographer Neil Ganju as part of the Estuarine Physical Response to Storms project. He is developing techniques to quantify the role of vegetation in the response and resilience of coastal areas to large storm events. Using a combination of numerical modeling techniques and field measurements, he will work to better understand how a variety of vegetation types modify waves and associated sediment-transport processes. Although coastal vegetation is generally thought to mitigate wave action and storm surge, the specific dynamics of the interaction remain poorly known; this work could ultimately help coastal planners understand the role of natural ecosystems in storm protection.
Telepresence Expedition Explores Unknown Deep-Sea Areas off of Puerto Rico and U.S. Virgin Islands
In April 2015, U.S. Geological Survey (USGS) scientists participated in a National Oceanic and Atmospheric Administration (NOAA) Ocean Exploration research cruise investigating unknown and poorly understood deep-sea areas off Puerto Rico and the U.S. Virgin Islands. An interdisciplinary team of scientists working at sea and on shore examined the geology and biodiversity along various seafloor features at depths ranging from 300 to 4,500 meters. Twelve dives were completed with a dual-bodied remotely operated vehicle (ROV) system consisting of the ROV Deep Discoverer (D2) and the Seirios camera platform, both of which were launched and controlled from the NOAA Ship Okeanos Explorer.
Oceanographer, Fran Lightsom, Receives Leadership and Innovation Award from the USGS Community for Data Integration
The U.S. Geological Survey (USGS) Community for Data Integration (CDI) presents its Leadership and Innovation Award to a community member for outstanding contributions in guiding USGS data integration activities through the CDI working groups. The award is meant to recognize someone who brings new ideas to life and provides unwavering leadership in producing tangible results that will improve data integration, access, and discovery. The awardee actively seeks collaborative approaches, embraces new perspectives, and provides a stimulating forum to address on-the-ground data integration needs of the community. Through this leadership, the awardee’s contributions move the CDI, and on a broader scale, the USGS and its partners, forward to a more integrated data landscape that ultimately advances USGS science.
Imaging Methane Seeps and Plumes on the U.S. Atlantic Margin
Scientists from the U.S. Geological Survey (USGS) Gas Hydrates Project surveyed methane seeps and plumes on the northern part of the U.S. Atlantic margin aboard the research vessel (R/V) Endeavor in April 2015. The researchers collected high-resolution seismic data (cross-sectional views of sediment layers and other features beneath the seafloor) along ship tracks totaling nearly 580 kilometers (360 miles), in addition to continuous imagery of methane plumes in the water column above seafloor cold seeps. They also measured the flux of methane and carbon dioxide (CO2) from the ocean to the atmosphere.
Dive In – Explore Thousands of Coastal and Seafloor Images
Thousands of photos and videos of the seafloor and coastline—most areas never seen before—are now available and easily accessible online. This is critical for coastal managers to make important decisions, ranging from protecting habitats to understanding hazards and managing land use.
This USGS portal is unique, due to the sheer quantity and quality of data presented. It is the largest database of its kind, providing detailed and fine-scale representations of the coast. The "geospatial context" is also unique, with maps displaying imagery in the exact location where it was recorded.
Imagery is available through the U.S. Geological Survey (USGS) Coastal and Marine Geology Video and Photograph Portal.
|This Woman ROCKS! Many people spend years trying to find their “dream job,” but USGS Marine Geologist, Dr. Laura Brothers, is one of the lucky few who has already found hers. |
What’s the most important advice Brothers has for young women thinking about pursuing a careerin science, technology, engineering, and/or math fields, known as STEM, which stands for Science, Technology, Engineering and Math. “Find a mentor,” Brothers says. “It goes for anybody going into any field. Finding somebody that can lead you along and show you the ropes makes a big difference. It can be tough to envision yourself in a field, if you don’t look like most of the practicing professionals, particularly when you’re starting out.”

|Widespread methane seepage from the seafloor on the northern US Atlantic margin. Natural methane leakage from the seafloor is far more widespread on the U.S. Atlantic margin than previously thought, according to a study by researchers from Mississippi State University, the U.S. Geological Survey, and other institutions.
The study, Widespread methane leakage from the sea floor on the northern US Atlantic Margin, by A, Skarke, C. Ruppel, M, Kodis, D. Brothers and E. Lobecker in Nature Geoscience is available on line.

| New Approaches for Storm Forecasting Combining models for a more robust way of understanding storms and their impacts. The USGS Coastal and Marine Geology Program recently sponsored training for nearly 90 scientists from over 15 countries to learn about a new modeling system designed to improve our ability to predict storms and their impacts. The system, called Coupled- Ocean-Atmosphere-Wave- Sediment Transport (COAWST) Modeling System, couples together several open-source modeling components that have been tailored to investigate processes of the atmosphere, ocean, waves, and coastal environment.

| #StrongAfterSandy—The Science Supporting the Department of the Interior’s Response. Dr. Neil K. Ganju, Woods Hole Coastal and Marine Science Center research oceanographer, speaks at Congressional Briefing.
Hurricane Sandy in October 2012 devastated some of the most densely populated areas of the Atlantic Coast. The storm claimed lives, altered natural lands and wildlife habitat, and caused millions of dollars in property damage. Hurricane Sandy is a stark reminder of our Nation's need to better protect people and communities from future storms. To inform the Department of the Interior's recovery efforts, the U.S. Geological Survey, National Park Service and U.S. Fish and Wildlife Service are collectively developing and applying science to build resilient coastal communities that can better withstand and prepare for catastrophic storms of the future.

| New Maps of the Massachusetts Seafloor. The U.S. Geological Survey and the Massachusetts Office of Coastal Zone Management (CZM) have worked collaboratively to map the geology of the shallow seafloor offshore of Massachusetts coast. Interpretation of high-resolution geophysical data (interferometric and multibeam swath bathymetry, lidar, backscatter, and seismic reflection), sediment samples, and bottom photographs were used to produce a series of maps that describe the distribution and texture of seafloor sediments, shallow geologic framework, and physiographic zones of this inner-shelf region.
The link to the first CZM interpretive report, Shallow Geology, Seafloor Texture, and Physiographic Zones of the Inner Continental Shelf from Nahant to Northern Cape Cod Bay, Massachusetts, is available at http://pubs.usgs.gov/of/2012/1157/
| Seismic-Imaging Research Cruise Investigates Deepwater Gas Hydrate Deposits in the Gulf of Mexico. Interest is mounting in the possibility that gas hydrate—a naturally occurring ice-like substance that contains vast quantities of methane—might be a viable source of natural gas. A research cruise by the U.S. Geological Survey (USGS) Gas Hydrates Project in the northern Gulf of Mexico in spring 2013 shed new light on that possibility.
