    Environmental Studies Program: Ongoing Study Title Impacts of Sedimentation and Drivers of Variability in the Boulder Patch Community, Beaufort Sea (AK-19-01) Administered by Anchorage, Alaska Office BOEM Contact(s) Rick Raymond [email protected] Conducting Organizations(s) University of Texas at Austin and UAF Total BOEM Cost $750,000 Performance Period FY 2019–2024 Final Report Due June 2024 Date Revised October 4, 2019 PICOC Summary Problem The Boulder Patch provides complex and unique habitat and supports high biodiversity in an area of considerable oil and gas interest, which includes the proposed construction of Liberty Island (less than half a mile away). Impacts of industry activity may smother/bury/kill productive biological area, but mitigation measures may be possible. Intervention This study will conduct a monitoring program to examine long-term drivers of community variability during Liberty development activities. In addition, it will test possible mitigation measures using common industry materials to “reseed” or replace habitat lost due to Liberty Island development activities. Comparison The post-development community structure will be compared against historic data to assess impacts of O&G activity. Further, artificial substrate will be compared to buried boulders to test efficacy of using industry materials to mitigate development impacts. Outcome Results will include defined spatial gradients and temporal trends in environmental conditions, benthic community structure, and kelp production in the Boulder Patch community; evaluation of the effect of sediments on Boulder Patch community; and assessment of test artificial substrates as possible habitat mitigation. Context Impacts of Sedimentation and Drivers of Variability in the Boulder Patch Community, Beaufort Sea (AK-19-01) BOEM Information Need(s): Impacts to the Boulder Patch from proposed gravel island construction were identified by local communities as a concern during scoping for Liberty Island.

The Flatirons were formed when the Permian/Pennsylvanian-aged sedimentary rocks of the Fountain Formation were tilted upward as the older rocks to the west rose during the Laramide Orogeny about 70 million years ago. Subsequent erosion has reduced those tilted slabs of the Fountain Formation to large, triangular slabs of rock that seem to lean up against the older rocks to the west of them.

  • 2016 Longshore Size Grading on a Boulder Beach
    LONGSHORE SIZE GRADING ON A BOULDER BEACH ANDREW GREEN, ANDREW COOPER, AND LESLEE SALZMANN ABSTRACT Longshore size sorting on boulder beaches has not previously been reported. In a boulder beach comprising beachrock slabs, we report systematic longshore clast size grading. The boulder beach at Mission Rocks, South Africa is deposited on an elevated (þ3 m MSL) shore platform and comprises imbricated clasts up to 5 m in the a-axis dimension (9 tonnes). The clasts are derived from adjacent intertidal beachrock and eolianite outcrops and are emplaced during high-magnitude wave events. Four distinct downdrift-fining cells are present. Each is 40–50 m long. The sorting is attributed to post-emplacement clast redistribution in which the smallest clasts are transported most frequently (by lower-magnitude storms) and therefore travel farthest downdrift. The updrift cell boundary is marked by boulders (5 m in length) that exceed the transport threshold for all but the most energetic of storms while the downdrift limit contains clasts 0.3 m in length. This mechanism of longshore size sorting does not rely on variations in longshore wave power as does cell development on sand and gravel beaches. The alongshore sorting via multiple high- (and variable-) magnitude events over a period of time, distinguishes these coarse clast deposits from those of single extreme events (whether storms or tsunamis). INTRODUCTION The longshore sorting of beach sediment by waves has received much attention. On sand and gravel beaches longshore sorting is manifest in variability of size (Komar 1977; Stapor and May 1983) and shape (Bluck 1967; Carr 1969; Carr 1971; Illenberger 1991) and may also be reflected in heavy- mineral distributions (Frihy and Komar 1991; Li and Komar 1992; Frihy and Lotfy 1997).

  • 1 El Niño and Intertidal Boulder Field Sedimentation at Point Reyes
    Blair Conklin El Niño Sedimentation Spring 2017 El Niño and intertidal boulder field sedimentation at Point Reyes National Seashore Blair Conklin ABSTRACT Wave-exposed boulder fields, a common feature of the California coast, encounter drastic fluctuations in the amount of sand within them. This study examined the inter-annual and seasonal differences of sedimentation in an intertidal boulder field from September 2014 to March 2017. The study period included one El Niño winter, characterized by increased wave energy, and two ENSO-neutral winters. I used monthly photographs to qualitatively monitor sedimentation at two intertidal boulder fields in northern California. Sand depth was also measured within the boulder fields, and those measurements were positively correlated to the photographic assessments of sedimentation. Only one of the sites exhibited a strong seasonal cycle in sedimentation. Additionally, there were no differences in sedimentation between El Niño and ENSO-neutral winters. The results of this study indicate that sedimentation and erosion on beaches can vary dramatically between adjacent shorelines based on physical factors, such as exposure to swell conditions. Monitoring and understanding coastal sedimentation can inform land management decisions, marine resource reserves, and erosional processes during climate anomalies. KEYWORDS sand; beach morphology; wave energy; intertidal; seasonal; El Niño; 1 Blair Conklin El Niño Sedimentation Spring 2017 INTRODUCTION Beach morphology can undergo drastic changes over time. Wave energy plays an important role in the transport of sediments and the transformation of sandy beach systems (Moore et al. 1999; Charlier et al. 1998; Cooper et al. 2013). Many regions of the California coast are exposed to wave energies that are produced from storms formed in the southern and northern hemispheres of the Pacific Ocean.

(2) Enhance geomorphic content and clarity of soil map unit descriptions by use of accurate, defined terms. (3) Establish consistent geomorphic term usage in soil science and the National Cooperative Soil Survey (NCSS). (4) Provide standard geomorphic definitions for databases and soil survey technical publications. (5) Train soil scientists and related professionals in soils as landscape and geomorphic entities. 629.1 Responsibilities This glossary serves as the official NCSS reference for landform, geologic, and related terms. The staff of the National Soil Survey Center, located in Lincoln, NE, is responsible for maintaining and updating this glossary. Soil Science Division staff and NCSS participants are encouraged to propose additions and changes to the glossary for use in pedon descriptions, soil map unit descriptions, and soil survey publications. The Glossary of Geology (GG, 2005) serves as a major source for many glossary terms. The American Geologic Institute (AGI) granted the USDA Natural Resources Conservation Service (formerly the Soil Conservation Service) permission (in letters dated September 11, 1985, and September 22, 1993) to use existing definitions. Sources of, and modifications to, original definitions are explained immediately below. 629.2 Definitions A.

  • All Grants Awarded Through Fiscal Year 2020 INTRODUCTION and KEY
    All Grants Awarded Through Fiscal Year 2020 INTRODUCTION AND KEY This report is a list of all grants awarded by the Colorado Historical Society’s State Historical Fund (SHF) since its inception in 1992 (state Fiscal Year 1993) through the end of Fiscal Year 2020. The amounts listed are the original award amounts. If for some reason the entire grant amount was not used (i.e. a project was terminated or was completed under budget) the full amount awarded will appear. In other instances grant awards were increased either to enable project completion or to cover the costs of easements. In these instances, the additional award amount is shown in a separate entry as an increase. In those cases where no work was accomplished and the funds were either declined by the grant recipient or were required to be returned to the SHF through rescissions, no entry will appear. For this reason, projects listed in one version of this report may not appear in later versions, and the financial information shown in this report may not be comparable to other revenue reports issued by the SHF. Grants listed in this report are identified by project ID number. The first two characters in the project ID number represent the fiscal year from which the grant was scheduled to be paid. The state is on a July 1 – June 30 fiscal year. So, for example, all grants made between July 1, 2006 and June 30, 2007 will be coded “07”. The next two characters identify the type of grant. In the case of grants that are awarded based on specific application due dates, the grant round in which the project was funded will be paired with either a letter or number.
