14 Eye-Opening USGS Images from 2014

As we wind down 2014, let’s refresh your science trivia knowledge and brighten your eyes and brain with a list of fun facts and gorgeous images from USGS.

We’ve picked out a few snapshots and videos from the 2014 year of USGS science — a tiny fraction of all the new discoveries, earthly phenomena, and new publications we worked on this past year. It’s impossible to encompass all that we survey for our nation on this planet and beyond, but we hope you enjoy this little visual morsel before we head into another new year. So let’s get started!

 

 

1. Hawaiʻi Hot Lava

After slowly moving downslope from Kīlauea Volcano’s East Rift Zone since June 27, 2014, this active lava flow in Hawaiʻi reached the town of Pāhoa just before Halloween, destroying roads, a cemetery, and private property in this community. Amazingly, the Pu‘u ‘Ō‘ō vent began erupting in 1983 and has continued erupting essentially nonstop for more than 31 years, though this recent flow was the first to threaten homes since 2012. In this photo from October 26, 2014, a USGS geologist is mapping the margin of the active lava flow in an open field west of the town of Pāhoa; the lava has continued its advance as of December.

Stay tuned to the USGS Hawaiian Volcano Observatory in January 2015 when they host the annual “Volcano Awareness Month” with many public education events on the Island of Hawaiʻi.

 

 

 

2. Volcano #TBT

If you can stand the heat, study geology! USGS is responsible for issuing “timely warnings” of potential volcanic hazards to emergency-management authorities and to the populace affected. In this photo, a USGS researcher is taking a temperature measurement on a sluggish channel eddy on Kīlauea Volcano in 1984. The research in Hawaiʻi is just one of many projects overseen by the USGS Volcano Hazards Program, which monitors active and potentially active volcanoes, assesses their hazards, responds to volcanic crises, and conducts research on how volcanoes work.

If you’ve been following USGS on Instagram in 2014, then you’ve already seen this crazy classic photo we posted in August as part of the “Throwback Thursday” meme.

3. The Largest Earthquake in U.S. History

Forget action movies with computer graphics — major earthquakes are a real phenomenon, and they impact real communities across our nation. March 2014 marked the 50th anniversary of the Great Alaska Earthquake, a magnitude 9.2 event that shifted land downward by 8 feet and upward as much as 38 feet in some locations. USGS scientists were immediately at the frontlines in 1964 studying this catastrophic earthquake — which led to some groundbreaking changes in geologic theories and paved the foundation for our current research and monitoring efforts of earthquakes in the United States.

Premiered in January, our documentary video “The Great Alaska Earthquake,” interviews those same USGS scientists and reflects on the scientific and natural hazard response lessons learned from 1964. (Film directed by Stephen Wessells/USGS)

 

 

 

4. Will I Be Shaken or Stirred?

In July 2014, USGS updated the U.S. National Seismic Hazard Maps, which reflect the best and most current understanding of where future earthquakes will occur, how often they will occur, and how hard the ground will likely shake as a result. Along with other data, the updates review new information on East Coast earthquakes, new California faults, and human-induced earthquakes, and helps local governments and communities improve public safety, building design, and insurance practices. (Map by USGS Geologic Hazards Science Center)

Earthquakes pose significant hazards to 75 million Americans in 39 States. The USGS has responsibility for recording and reporting earthquake activity nationwide, and also tracks earthquakes worldwide. And while citizens, emergency responders, and engineers rely on the USGS for accurate and timely information on earthquake events, USGS also relies on you, the public — whenever you fill out the Did You Feel It survey online — which provides valuable data on earthquakes to our scientists!

 

 

 

5. Yttrium on the Soles of Your Shoes

If you’re admiring the glow of LED tree lights or watching your favorite football team on your LED television this winter season, you have yttrium to thank for that. Named in the 1700s after the Swedish village Ytterby, yttrium is one of the “rare earth elements” very much needed for human technology. The elements yttrium, europium, and terbium are used in fluorescent and LED lighting and televisions.

In May 2014, USGS scientists finished compiling the Geochemical and Mineralogical Maps for the Soils of the Conterminous U.S. — an extraordinary dataset charting the abundance and distribution of chemical elements and minerals — including yttrium — in soils throughout the lower 48 U.S. states at three different soil horizons. This astounding achievement represents a baseline from which any future changes to our soil chemistry may be detected and measured against — information which can improve our nation’s agriculture, land-use planning, and even law enforcement.

6. A Cartographer of Mars

In July 2014, USGS completed a global Geologic Map of Mars for our colleagues at NASA. You heard that right — USGS not only creates maps of Earth, but of other planets, too! Using data from the Mars Global Surveyor and Mars Odyssey probes, this is the best map currently available of the geologic units and landforms on the Red Planet. (Map by USGS Astrogeology Science Center)

Maps like these are the work of the USGS Astrogeology Research Program, which works with NASA and other institutions to select landing sites, create mission maps, and carry out scientific investigations on planetary missions. So the next time you look at a Martian or Lunar map online or in your hands, squint and see if you can find the USGS name in the map credits!

 

 

 

7. Watching Over Earth

Of course, USGS is best known for training its eye on the changes and rhythms of Planet Earth. Much of this work is thanks to the Landsat Missions, a joint program between USGS and NASA, wherein the USGS operates satellites that help us scan the Earth’s surface for natural and man-made changes. The first satellite, Landsat 1, was launched in 1972, and the latest mission, Landsat 8, celebrated its first birthday on February 11, 2014.

The Landsat missions have now collected over 42 years of global land imagery data. One benefit of this incredible record is the ability to visualize landscape conditions, such as drought impacts to California. The decrease of winter snow cover in the Sierra Nevada Mountains can be seen in this progression of images, captured by Landsat in February 2011, 2013, and 2014. California is heavily dependent on large Sierra Nevada snowpacks to replenish its annual water supply and sustain its vast agricultural lands and diverse ecosystems, and this satellite record underscores the current water shortage plight of the Golden State.

8. Top of the Topo

USGS has always been known for its maps, and we are still in the business. However, topographic maps — the essential tool for planners, hikers, emergency response crews, and other professionals and enthusiasts — have caught up with the digital age. US Topo Maps are now delivered in PDF format with geospatial extensions via GeoPDF®, which allows layers of information to be turned on or off, and provides flexible zooming and printing options. Our maps are available as free downloads via the USGS Map Locator at the USGS Store, making it easy for anyone to grab map PDFs for their tablets or smartphones before heading out for some outdoor sightseeing.

And what were the most downloaded US Topo Maps in 2014? At the top is the Washington West quadrangle, featuring the District of Columbia. Other interesting top downloads include Santa Fe, New Mexico; Moab, Utah; Central Park in New York and Yuma in Michigan!

9. Attack of the Hydrologist Clones

No, USGS isn’t cloning hydrologists or hiring lesser-known X-Men to do science. This is a time-lapse composite photograph from December showing a USGS technician crossing a stream near Thompson Falls, Montana, to measure water flow at different points across a stream transect. This is just one of the many scientific duties of the USGS Water Mission Area. (Photo by Dan Hess/USGS)

USGS provides NOAA’s National Weather Service with stream data for critical flood warnings. Additionally, these stream surveys allow scientists to compute the streamflow of rivers across the United States, and help with fish habitat restoration, and other ecosystem studies. Advanced computer models and long-term analyses are of little use without the data collected by technicians and scientists working long, hard days in the field!

 

 

 

10. Dreaming of Streams in Green

USGS operates about 7,400 streamgages around the United States, including this gage photographed in August 2014 in the serene, verdant woods of Little Back Creek, located within the George Washington National Forest in Virginia. You can find this photo in the USGS Flickr gallery. (Photo Credit: Alan Cressler/USGS)

Streamgages are operated by the USGS National Streamflow Information Program (NSIP), whose mission is to provide real-time streamflow data to local, state, regional, and national leaders, so communities can continuously monitor changes in their local waters, track drought and flood conditions, and manage accordingly.

 

 

 

 

11. Interactive Energy

Investigating natural sources of energy has always been a task for USGS, helping our nation study and assess the location, quantity, and quality of energy resources, including the economic and environmental effects of resource extraction and use. From the exploration assessment of oil and natural gas to habitat restoration after dam removals, USGS has evolved with the changing needs and considerations of energy use in the United States.

In February 2014, USGS unveiled windFarm, an interactive app mapping wind energy turbines around the United States, visualizing a never-before-assembled national dataset for anyone to access online. Knowing the location of individual turbines, their make, model, height, blade area, and capacity offers important information for land and resource managers and scientists studying wildlife-turbine collisions or interactions between wind turbines and ground-based radar.

12. Bee Butts Break the Internet?

Not quite, but they are still amazing to look at! This macrophotograph uploaded in November 2014 shows the bee-hind of a “plain sweat bee” (Lipotriches spp.) collected from Australia. This stunning image is part of the collection made by the USGS Native Bee Inventory and Monitoring Program, which develops identification tools for native bee species in the United States and elsewhere. This virtual museum provides a critical service for scientists studying bees around the world, their role in the pollinating our plants and crops, and why they are suffering from declines. (Photo by USGS Native Bee Inventory and Monitoring Program)

USGS also manages similar monitoring programs and information hubs on other species issues, including amphibian decline (Amphibian Research and Monitoring Initiative) and aquatic invasive species (Nonindigenous Aquatic Species).

 

 

 

13. From a Polar Bear Point of View

This is no footage from a soda pop television commercial: A USGS researcher attached video cameras to four female polar bears as part of a study on how bears expend their energy. In this video cut we posted online in June 2014, you can see polar bears swim in arctic waters, tackle a dead seal meal — and nuzzle with another bear.

Combined with satellite telemetry data, behavior observations like this help scientists understand how much food and rest bears need to survive, and whether environmental change like decreased sea ice are stressing this threatened species. The ongoing research is part of the USGS Changing Arctic Ecosystems Initiative, one of many USGS research programs on wildlife populations, climate change, and land use change.

Tidepool scenes of vibrantly colored sea stars could become a rarity as the Sea Star Wasting Disease spreads.

14. Falling Sea Stars

Tidepool scenes of vibrantly colored sea stars like this one in San Juan Islands, Washington, could become a rare sight as the Sea Star Wasting Disease spreads. The disease causes sea stars to fall apart and disintegrate within days, and has been killing these sea creatures in droves from Mexico to Alaska. In November 2014, a new Cornell University study with assistance from USGS scientists finally pointed to a prime suspect in the deadly epidemic: a previously unknown virus.

Research and monitoring of ecosystem trends, water resources, natural hazards, environmental health, and climate change are important elements of the USGS mission, which has grown from its roots in geology and mapping. Today’s USGS looks much different than the one that began 135 years ago under President Rutherford B. Hayes, and the scientific methods and survey scope our agency is charged with today were probably undreamed of in the 1870s — now in all 50 states and U.S. territories, with partner nations around the world, and on other planetary bodies in the Solar System.

So look around in our changing world — you’ll be surprised where you can find USGS!
