Earth Science Week 2013 Events

October 13-19 is Earth Science Week 2013! This year’s national theme for the week is “Mapping Our World,” and each day of the week focuses on specific themes (see http://www.earthsciweek.org/specialdays.html). Every year, NBMG actively participates and hosts events in conjunction with Earth Science Week.

Earth Science Week Field Trip – October 12 and 13
NBMG hosts annual Earth Science Week field trips, which are educational, free, family oriented, and always a lot of fun. In keeping with the national Earth Science Week theme, this year’s trip will focus on identifying rocks and minerals, then mapping the geology around NBMG’s Great Basin Science Sample and Records Library (GBSSRL) on the DRI campus. The trip will take place on October 12 and 13 (same trip on Saturday and Sunday).  A sign-up form and additional information is available at http://www.nbmg.unr.edu/ESW/ESW_13/index.html.

International EarthCache Day – October 13
Sunday, October 13 is International EarthCache Day. Celebrate by hunting Nevada EarthCaches available from the NBMG website! http://www.nbmg.unr.edu/ScienceEducation/EarthCaches/EarthCaches.html

National Fossil Day – October 16
Plan a fossil-collecting adventure using a field guide from a past NBMG Earth Science Week trip to celebrate the fourth annual National Fossil Day on Wednesday, October 16. Visit Geotripping in Nevada on the NBMG website and look for field guides with numbers E28, E40, E42, and E52. You could also plan a trip to visit an excavation site for Nevada’s state fossil—the ichthyosaur—at Berlin-Ichthyosaur State Park, or visit the huge plesiosaur and other fossils at the W.M. Keck Museum on the UNR campus. If you attend the ESW trip on October 12 or 13, which leaves from the GBSSRL, you can pick up some free games and activities on fossils at our office.

The Great Nevada ShakeOut – October 17
On Thursday, October 17 at 10:17 a.m., you can join NBMG in practicing how to “drop, cover and hold on” during The Great Nevada ShakeOut. Learn more about this statewide earthquake drill and how to participate at http://www.shakeout.org/nevada/index.html. Don’t forget that Nevada is earthquake country, so take the necessary steps to be prepared for the next time an earthquake strikes! Earthquake preparedness brochures and booklets are available free on the NBMG website at http://www.nbmg.unr.edu/Geohazards/Earthquakes/Preparedness.html.

Geologic Map Day – October 18
Friday, October 18 is Geologic Map Day. A major component of NBMG is geologic mapping. Geologic maps are critical to understanding Nevada’s geology and landscapes, mineral and energy resources, and geologic hazards. NBMG’s extensive collection of geologic maps can be browsed online at http://www.nbmg.unr.edu or in person at the GBSSRL.

Be sure to participate in Earth Science Week 2013, and don’t forget to sign up for our annual field trip!

USGS Webinars

The USGS National Geospatial Program team for CA, NV, and HI (Drew Decker and Carol Ostergren) is hosting a series of webinars over the next several months. These webinars will highlight USGS National Geospatial Program advances and new technologies being deployed by other Federal agencies. Please feel free to forward this webinar announcement to others in your organizations. Both of these webinars require advance registration, but we will keep this open as long as possible.

October 3, 1 pm Pacific: The USGS Volunteered Geographic Information Program

The volunteer effort of The National Map Corps to collect and improve structures data provides several benefits to the Program and its users:

  • Participation in The National Map Corps is easy. Complete registration instructions and editing guidelines can be found at https://my.usgs.gov/confluence/display/nationalmapcorps/Home
  • The National Map Corps benefits the agency and the participants by providing opportunities for citizen participation in USGS science
  • Participation in The National Map Corps raises geographic awareness and improves users’ skills in using web-based tools
  • Volunteer participation improves public access to data and data quality

The use of The National Map Corps and VGI will result in more complete national datasets in The National Map with improved positional and attribute accuracy. With this coordination, federal, state, and local government efforts, combined with citizen contributions, are complementary and lead to a richer dataset that is available for everyone to use.

TOPIC: USGS Volunteered Geographic Information
DATE: Thursday, October 3, 2013
TIME: 1:00 pm, Pacific Daylight Time (San Francisco, GMT-07:00)

NBMG Talks – Geoff Blewitt – Monday Sept 23

Title: Observed Solid Earth Contributions to Sea Level Variation in Western US

Speaker: Geoff Blewitt, Nevada Bureau of Mines and Geology, University of Nevada, Reno
http://www.nbmg.unr.edu/Staff/Blewitt.html

Date:  Monday September 23, 2013 (lecture at 4:00, picnic to follow at Idlewild Park)

Place:  DMS (Davidson Math and Science Center) Room 102 on the UNR campus
http://www.unr.edu/around-campus/maps

Abstract: Satellite altimetry over the last two decades has measured variations in geocentric sea level (GSL), allowing us to test models of physical oceanography and global climate change. Global mean GSL is currently rising the level of ~3 mm/yr, and appears to be accelerating. The societal impacts of sea level change however relate to variations in local sea level (LSL), relative to the land at the coast. Therefore, assessing the impacts of sea level change requires coastal measurements of vertical land motion (VLM). Indeed, ΔLSL = ΔGSL -ΔVLM, with subsidence mapping 1:1 into LSL.

Here GPS geodetic data are used within 15 km of the US west coast to infer regional, secular VLM, which is found to have different behavior north and south of the Mendocino Triple Junction (MTJ). The California coast has a coherent regional pattern of subsidence averaging 0.5 mm/yr, with an increasing trend to the north. This trend generally matches GIA model predictions of forebulge collapse. Around San Francisco Bay, the observed coastal subsidence of 1.0 mm/yr coherently decreases moving away from the Pacific Ocean to very small subsidence on the east shores of the bay. This gradient is likely caused by San Andreas-Hayward Fault tectonics, and possibly by differential surface loading across the bay and Sacramento-San Joachim River Delta. Thus in addition to the trend in subsidence from GIA going northward along the California coast, tectonics may also play a role where the plate boundary fault system approaches the coast.

In contrast, VLM of the coast north of the MTJ in Oregon and Washington is found to have the opposite sign (uplift) and varies with distance between the coast and the trench. The uplift peaks at 2-3 mm/yr in northern Washington. This pattern can be explained by elastic strain accumulation at the locked subduction zone, coupled with a contrast in rheological structure affecting GIA.

In terms of LSL and hence societal impact, the observed mean California subsidence of 0.5 mm/yr approximately cancels with GIA predictions of global GSL lowering at a similar rate. This GSL lowering is caused by “continental levering,” in which the volume of ocean basins is increasing today as the mantle flows away from under the oceans in isostatic response to >100 m of sea level rise following Pleistocene deglaciation. So the net LSL in California caused by coastal VLM plus GSL lowering by GIA is ~0.5 mm/yr LSL rise to the north, and ~0.5 mm/yr lowering to the south. In northern Washington, the net LSL is inferred to be lowering at a rate of ~3 mm/yr.

This methodology establishes a base level of LSL on top of which will be the imprint of global sea level rise from global climate change, including ice-sheet melt, thermal expansion, and changes in ocean and atmospheric circulation. Our observed regional variation in land motion are of similar magnitude as the effects of global change on sea level, and so we conclude that VLM must be taken into account. Given that UNR’s GPS time series are selected from a globally consistent set from >11,000 stations (the largest such dataset in the world), this methodology could be applied in a seamless way over coastlines across the globe, depending on available station coverage.
