GeoHealth will foster the intersection of Earth science disciplines (Earth processes, climate change, atmospheric and ocean sciences, hydrology, among others), with those of the health sciences, defined broadly (environmental and ecosystem health and services, human and agricultural health, geomedicine, and the impact of natural hazards). Now Accepting Applications for Two Editors in Chief of GeoHealth

AGU is launching GeoHealth under Founding Editor Rita R. Colwell. We are seeking applications for two dynamic, well-organized scientists with high editorial standards and strong leadership skills to serve 4-year terms as the editors in chief (EICs) to lead this exciting journal starting in 2017 and beyond. One editor’s main area of focus will be on the geosciences, while the other editor’s main area of focus will be on health. This is an important opportunity to help shape and lead this increasingly important, cross-cutting discipline. The EICs will be the principal architects of the scientific content of the journal. They are active scientists, well-known and well-regarded in their respective discipline. The EICs must be active in soliciting the best science from the best scientists to be published in the journal. Working with the other editors and AGU staff, EICs are the arbiter of the content of the journal. Among other functions, EICs will be responsible for: • Acting as an ambassador to the author/editor/reviewer/scientist community. • Setting the strategy for the journal. • Leading the editor selection process. • Assigning and balancing review work load. • Making decisions related to scientific ethics. • Reviewing and contributing to periodic monitoring reports. • Conducting and attending meetings.

If you would like to be considered for one of the Editor in Chief positions of GeoHealth, send your curriculum vitae with a letter of interest via email to [email protected]. If you would like to nominate a highly qualified colleague, send a letter of recommendation to the same email address. Please make sure that you specify GeoHealth in the subject line of the email.

Newly Found Dwarf Planet Points to Solar System’s Chaotic Past

Currently located nearly 10 billion kilome- ters away toward the constellation Pisces, 2015 RR245 is swooping inward for a ­close-​­up in 2096. Extrapolating from its estimated distance and likely composition, 2015 RR245 is roughly 700 kilometers in diameter. At just one third the size of Pluto and one fifth the size of the Moon, the newfound object is on the low end of the dwarf planet spectrum. The International Astronomical Union coined the term dwarf planet in 2006 to describe objects, like Pluto, that aren’t proper planets. A dwarf planet must circle the Sun and be massive enough to pull its own weight into a rough sphere. Although the research team hasn’t observed 2015 RR245’s shape, its diameter suggests that it’s likely heavy enough to be roughly spherical. But unlike the proper planets, it hasn’t necessarily cleared the orbital neighborhood of debris.

Still, scientists don’t understand the specif- ics of Neptune’s early migration. “Did it hap- USGS Seeks to Contain Damage pen fast?” asks Bannister. “In less than a few tens of millions of years? Or did it take as much from Scientific Misconduct at Lab as several hundreds of millions of years?” To answer these questions, scientists have to build models of the early solar system, run each through 4.5 billion years of history, and see if it creates the thousands of orbits—of planets, dwarf planets, asteroids, and com- ets—pinpointed today. If one of these models lands on today’s snapshot, researchers may have their solution. But until then, every extra orbit helps.

A Cold Start These icy objects can shed light on not only the solar system’s chaotic evolution but also its frigid formation. Unlike the inner planets, which have been warmed by the Sun or their own internal heat, the distant and small objects are cold enough to have preserved some of the chemical ingredients that were present when the solar system formed. “It’s like archeology,” said Scott Sheppard, an astronomer at the Carnegie Institution for Science in Washington, D.

Only one study presented at the meeting had sufficient data to link the timing of disease outbreak to the occurrence of storm flow that mobilized con- taminant migration into groundwater supplies used for drinking. More commonly, scientists rely on simplistic geographic associations between groundwater contamination and disease outbreak. Given the ­place-​­based nature of hydrogeological studies, we recommend that spatially distributed health data be reported to help reveal the intersection of water quality and human health. Participants discussed ways that general regulations for water quality protection may not be appropri- ate in karst regions, where contaminants are transmitted rapidly from the land surface to the water table, and they debated creative non- regulatory approaches to managing land use as another means of protecting water supplies.

he global nature of climate change means that all environments show evidence of abnormal change: continually rising average tempera- tures and increases in sea level that inundate coastal areas, along with an increase in the fre- quency and intensity of severe weather such as hurricanes, typhoons, and tropical storms. TNew technologies provide ever clearer images and more detailed data on these effects and how they evolve from year to year. One such technology, lidar, is the laser equivalent of radar. The instrument sits aboard an aircraft that flies back and forth over an area, collecting data that are processed to produce a three- dimensional image of the surfaces below. The latest version of lidar collects data from three lasers at once, producing multispectral images that catch details a single- laser scan would miss. Geoscientists are putting this new capability to work, monitoring landscape features crafted by melting ice in frigid regions, providing data for storm surge and sea level rise models for the Gulf of Mexico, and monitoring an eco- system’s recovery from a massive oil spill.

Earth & Space Science News Eos.org // 11 technology have enabled breakthroughs in various fields of the geosciences [­Fernandez-​ ­Diaz et al., 2013]. The first airborne mapping lidar instru- ments were developed in 1966 to map Arctic pack ice [Ketchum, 1971] and hunt for subma- rines [Sorenson et al., 1966]. However, it was not until the end of the 1990s that the enabling technologies—­ including​­ satellite systems, navigation sensors, lasers, and detectors—were mature enough to produce the high resolution and accuracy in the topo- graphic data that geophysical research requires [Slatton et al., 2007]. During an airborne lidar survey, an aircraft outfitted with a laser emitter and a sensor scans a swath of surface below the flight path. Laser pulses, emitted at rates of hundreds of thousands of pulses per second, bounce back from the surface below, and these “returns” are picked up by the lidar sensor. By analyzing how long it takes the laser’s pulse to return to the sensor, a computer can determine the dis- tance to the reflecting surface. Simultane- ously, GPS receivers and inertial measuring units collect position and orientation data that enable determination of the aircraft’s trajec- tory to within 10 centimeters. Later, the range data are combined with air- craft trajectory and other data to produce a highly accurate “point cloud,” a set of data points containing information on the ­three-​ ­dimensional coordinates of the reflecting sur- face and the intensity, or relative strength, of each recorded return. Algorithms classify the likely sources of the returns as vegetation, artificial structures, ground surfaces, or other sources. Further processing of the point cloud generates digital elevation models. Depending on the science requirements, flight plans and sensor config- urations can provide digital elevation models of the topography at resolutions of a few tens of centimeters horizontally and a few centi- meters vertically [Glennie et al., 2013]. Traditional mapping lidars provide rich and accurate ­three-dimensional​­ data (Figure 1a) as point clouds and digital elevation models. They also produce “intensity” images that are the equivalent of aerial black-­ and-​­ white​­ pho- National Center for Airborne Laser Mapping National Center for Airborne Laser tographs (Figure 1b).

Titan has an advantage over traditional ALS systems for mapping areas like the McMurdo Dry Valleys, where areas of soil and snow overlap. A traditional ALS operating at 1550 nm would obtain strong returns from the soil surfaces but would have dif- ficulties obtaining returns from the ice and snow, which reflect little light at that wavelength.

Disasters of Human Origin Titan’s multispectral data are being used to study other environmental issues, including monitoring the evolution of ecosystems affected by the Deepwater Horizon oil spill in the Gulf of Mexico in 2010. Five years after this environ- mental disaster, NCALM was called upon to assist in map- ping wetlands in the Barataria Bay system along Louisi- ana’s Gulf Coast. In this project, researchers from the Coastal Waters Consortium (http://cwc​­ .​ lumcon­ .​ edu)­ plan to supplement lidar data with hyperspectral imaging data, which produce not only images but also the light spectrum of each pixel in the image. The hyperspectral data will be used to evaluate the presence or absence of pollutants, as well as the gen- eral health of the vegetation. Titan’s spatial data will be used primarily to estimate the biomass of the vegetation, and researchers will also assess how its active ­three-band​­ multispectral data can complement the passive hyperspec- tral data. Information gathered in the survey will be used to study how the ecosystem responds to and evolves from exposure to the oil spill. Data processing and analysis for this ­first-year​­ deploy- ment are still under way, and we will publish our results in science and engineering journals. We are hopeful that this new sensor and the enhanced spatial and spectral infor- mation it provides will lead to new applications and dis- coveries in the geosciences.

New Geophysical Research Letters Editorial and Revisions Policies

“major revisions” editorial decision. For these decisions, the manuscript number is main- tained, and authors are required to submit their revisions within 30 days of the decision. Once the revision is received, the editor may make a decision based on the revisions or may send the revised manuscript for re-review. For any manuscript sent for re-­ review,​­ the editor may choose to use the previous reviewers and/ or one or more new reviewers. This delibera- tion depends on reviewer availability and on the nature of the previous reviews, the authors’ responses, and the authors’ revi- sions. This new major revisions decision type does not replace other decision types used at GRL but merely adds to them.

A New Tool to Better Forecast Volcanic Unrest

Here Tonini et al. present a new model that includes indicators of nonmagmatic unrest that might help forecast when a phreatic eruption is soon to occur. The model is the Bayesian Event Tree, a probabilistic tool that synthesizes information from multiple sources—historical records, geological data, and analytical modeling—into one complete analysis that helps scientists forecast that an eruption may happen soon. The researchers built the new model using data from Indonesia’s Kawah Ijen, an active crater lake underlain by a degassing volcano and the perfect example of a system likely to experience phreatic erup- tions. Local sulfur miners are often killed by fumes of hydrogen sul- fide and sulfur dioxide that vent without warning from fissures in rock. Even in less dramatic events, these poisonous gases are still concentrated enough to burn the miners’ eyes and throats and even- tually dissolve their teeth. The team used data from 2000 to 2010 to establish a historical base- line of activity at Kawah Ijen and then analyzed the unrest events that occurred throughout the following 2 years. The model captured a swarm of earthquakes in May 2011 that suggested that Kawah Ijen was about to enter a long period of unrest. Indeed, further earthquakes in October
