USGS Continues to Write History

USGS Newsroom Technical - Fri, 04/17/2015 - 13:59
Summary: The fourth volume of the comprehensive history of the U.S. Geological Survey, Minerals, Lands, and Geology for the Common Defence and General Welfare: Volume 4, 1939‒1961, has been issued as an electronic document. New Volume of Agency Annals Released

The fourth volume of the comprehensive history of the U.S. Geological Survey, Minerals, Lands, and Geology for the Common Defence and General Welfare: Volume 4, 1939‒1961, has been issued as an electronic document.

Featuring more than 200 illustrations, the 704-page Volume 4 focuses on the United States and the USGS in war and peace from the beginning of World War II in Europe to the end of the administration of President Dwight D. Eisenhower. During this period, the USGS developed and adapted new instruments and methods that included airborne magnetometers and radiometers, advanced seismometers, stereoscopic plotters for topographic mapping, geophysical logging (detailed records of geologic formations penetrated by a borehole), and geological sampling from deep wells. 

The late Mary C. Rabbitt (1915‒2002), a geophysicist who served with the USGS (1949‒1978), wrote the first three volumes in the series: Volume 1, Before 1879 (1979), Volume 2, 1879‒1904 (1980), and Volume 3, 1904‒1939 (1986). Volume 4 was begun by Rabbitt and completed by coauthor Clifford M. Nelson, a geologist with the USGS since 1976. 

Like the earlier books in the series, Volume 4 places USGS operations in mapping and the earth sciences within the wider contexts of national and international history. For instance, USGS development of the airborne magnetometer — an instrument that traces the Earth’s magnetic field, enabling an effective method of exploring for subsurface minerals — followed from a wartime device that U.S. forces used to hunt enemy submarines in World War II. 

In the foreword to Volume 4, Mark D. Myers, the 14th USGS Director (2006‒2009), wrote that the volume records USGS support of the Nation’s efforts during "a pivotal interval of transformation for the United States and the agency, …a time of great national sacrifice, rapid expansion of industrial capacity, spectacular scientific and technological advancement, and international leadership."

Model Offers More Ease, Precision for Managing Invasive Asian Carp

Summary: The likelihood of Asian carp eggs being kept in suspension and hatching in the St. Joseph River in Michigan has been further evaluated using a model that examines a range of multiple flow and water temperature scenarios

The likelihood of Asian carp eggs being kept in suspension and hatching in the St. Joseph River in Michigan has been further evaluated using a model that examines a range of multiple flow and water temperature scenarios. Results illustrate the highest percentage of Asian carp eggs at risk of hatching occurs when the streamflow is low and when the water temperature is high. This new study by the University of Illinois and the U.S. Geological Survey is published in the Journal of Great Lakes Research.

“In this study, the Fluvial Egg Drift Simulator (FluEgg) model allowed us to examine the complex dependencies between flow, temperature and egg development,” said USGS hydrologist Ryan Jackson. “This information provides resource managers with a range of conditions under which the St. Joseph River is vulnerable to Asian carp reproduction."

The FluEgg model was used to evaluate egg movement and the likelihood of successful Asian carp reproduction under different streamflow and temperature conditions representative of historical spawning seasons in the St. Joseph River, a tributary to Lake Michigan. Results show that eggs develop faster at warmer water temperatures, therefore requiring less time to drift in the river until hatching. Low streamflows can also be conducive to reproduction when the streamflow is just fast enough to keep most of the eggs in suspension while allowing for the greatest amount of drift time before reaching the lake, thus increasing the likelihood of hatching.

The FluEgg model, developed by University of Illinois researchers in collaboration with the USGS, was first introduced in 2013. The latest version of the model is available online, and includes a user-friendly interface and improved predictions of egg transport in rivers.

Invasive Asian carp consume plankton from the base of the food web and reproduce prolifically which could pose substantial environmental risks and economic impacts to the Great Lakes if they become established. 

"This work focuses on the early life stages of Asian carp," said USGS research fish biologist Duane Chapman. "Targeting early life stages can include disrupting spawning activities or egg development in rivers where Asian carp spawn."

Several factors affect the viability of the eggs. The temperature of the water affects how long the eggs need to hatch, and the velocity of the river affects the movement of the eggs and whether the eggs remain in suspension or sink to the bottom. Eggs that settle on the riverbed will likely die, and eggs that are transported down the river and into a lake may not have enough time to develop to the hatching stage before settling to the lakebed.

The reproduction assessment of Asian carp eggs in the St. Joseph River demonstrated the complexity of the problem where the length of the river, velocity and water temperatures cannot be assessed individually. Rather, a holistic analysis is required, where egg development, water-quality characteristics and the hydrodynamics of the river are interconnected and analyzed together. 

“Successful reproduction requires a fine balance between the rate of egg development and the variable flow conditions present in a river required to maintain the eggs in suspension,” said Tatiana Garcia, USGS research hydrologist and lead author of the paper.

The paper, “Application of the FluEgg model to predict transport of Asian carp eggs in the St. Joseph River (Great Lakes tributary)” by Tatiana Garcia, Elizabeth A. Murphy, Patrick R. Jackson and Marcelo H. Garcia, is available online.

Do You Like to Map? Take the Mapping Challenge!

USGS Newsroom Technical - Wed, 04/15/2015 - 09:30
Summary: Volunteer citizen-mappers continue to make significant contributions to the USGS ability to provide accurate mapping information to the public The USGS crowd-sourcing project volunteers have updated all law enforcement points in Tennessee

Volunteer citizen-mappers continue to make significant contributions to the USGS ability to provide accurate mapping information to the public. Recently, volunteers were asked to update all of the law enforcement structure points in Tennessee. The volunteers answered the call and added, verified, edited, or deleted an amazing 440 points!

In addition, all of the points were quality checked by either a peer reviewer or an advanced editor, so the data was ready to go into The National Map at the conclusion of the challenge.

The volunteer additions and edits will be symbolized on US Topo maps during the next production cycle for Tennessee, slated for next year.

An exciting addition to the mapping project is Mapping Challenges. The Challenges asks volunteers to concentrate on specific areas and structure types that need updating. In addition, Challenges encourage volunteers to remain engaged, and incentivizes participation. Once a need is determined, a call to action goes out to the volunteer corps with information on the geographic location and the type of structures that needs updating. Volunteers who participate can earn a series of virtual recognition badges and are recognized on social media and TNMCorps project site.

Using crowd-sourcing techniques, the USGS Volunteered Geographic Information (VGI) project, known as The National Map Corps (TNMCorps), encourages volunteers to collect manmade structures data in an effort to provide accurate and authoritative spatial map data for the National Geospatial Program’s web-based The National Map. Structures being updated include schools, hospitals, post offices, police stations and other important public buildings.  

Special thanks to the volunteers who participated in this challenge: fconley, HGeisler, Cartograsaurus, TheJ, BCook2, rjerrard, Vindalou, Jwo_rocks, wesward, and alherna4.

"At times, locating structures seems similar to solving puzzles or detective work,” commented fconely, a Challenge veteran and one of the project’s more active participants.

Tools on TNMCorps project site explain how a volunteer can edit any area, regardless of their familiarity with the selected structures, and becoming a volunteer for TNMCorps is easy; register by going to The National Map Corps Editor. If you have access to the Internet and are willing to dedicate some time to editing map data, we hope you will consider participating.
