    Description: Abstract Observations of seismic anisotropy can provide direct constraints on the character of mantle flow in subduction zones, critical for our broader understanding of subduction dynamics. Here we present over 750 new SKS splitting measurements in the vicinity of Mount St. Helens in the Cascadia subduction zone using a combination of stations from the iMUSH broadband array and Cascades Volcano Observatory network. This provides the highest density of splitting measurements yet available in Cascadia, acting as a focused “telescope” for seismic anisotropy in the subduction zone. We retrieve spatially consistent splitting parameters (mean fast direction Φ: 74°, mean delay time ∂t: 1.0 s) with the azimuthal occurrence of nulls in agreement with the fast direction of splitting. When averaged across the array, a 90° periodicity in splitting parameters as a function of back azimuth is revealed, which has not been recovered previously with single‐station observations. The periodicity is characterized by a sawtooth pattern in Φ with a clearly defined 45° trend. We present new equations that reproduce this behavior based upon known systematic errors when calculating shear wave splitting from data with realistic seismic noise. The corrected results suggest a single layer of anisotropy with an ENE‐WSW fast axis parallel to the motion of the subducting Juan de Fuca plate; in agreement with predictions for entrained subslab mantle flow. The splitting pattern is consistent with that seen throughout Cascadia, suggesting that entrainment of the underlying asthenosphere with the subducting slab is coherent and widespread.

    Description: Atmospheric carbon dioxide concentration is expected to exceed 500 parts per million and global temperatures to rise by at least 2 degrees C by 2050 to 2100, values that significantly exceed those of at least the past 420,000 years during which most extant marine organisms evolved. Under conditions expected in the 21st century, global warming and ocean acidification will compromise carbonate accretion, with corals becoming increasingly rare on reef systems. The result will be less diverse reef communities and carbonate reef structures that fail to be maintained. Climate change also exacerbates local stresses from declining water quality and overexploitation of key species, driving reefs increasingly toward the tipping point for functional collapse. This review presents future scenarios for coral reefs that predict increasingly serious consequences for reef-associated fisheries, tourism, coastal protection, and people. As the International Year of the Reef 2008 begins, scaled-up management intervention and decisive action on global emissions are required if the loss of coral-dominated ecosystems is to be avoided.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Hoegh-Guldberg, O -- Mumby, P J -- Hooten, A J -- Steneck, R S -- Greenfield, P -- Gomez, E -- Harvell, C D -- Sale, P F -- Edwards, A J -- Caldeira, K -- Knowlton, N -- Eakin, C M -- Iglesias-Prieto, R -- Muthiga, N -- Bradbury, R H -- Dubi, A -- Hatziolos, M E -- New York, N.Y. -- Science. 2007 Dec 14;318(5857):1737-42.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Centre for Marine Studies, University of Queensland, St. Lucia, 4072 Queensland, Australia. oveh@uq.edu.au〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/18079392" target="_blank"〉PubMed〈/a〉

    Description: The western United States is experiencing a severe multiyear drought that is unprecedented in some hydroclimatic records. Using gridded drought reconstructions that cover most of the western United States over the past 1200 years, we show that this drought pales in comparison to an earlier period of elevated aridity and epic drought in AD 900 to 1300, an interval broadly consistent with the Medieval Warm Period. If elevated aridity in the western United States is a natural response to climate warming, then any trend toward warmer temperatures in the future could lead to a serious long-term increase in aridity over western North America.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Cook, Edward R -- Woodhouse, Connie A -- Eakin, C Mark -- Meko, David M -- Stahle, David W -- New York, N.Y. -- Science. 2004 Nov 5;306(5698):1015-8.

    Description: The ocean moderates anthropogenic climate change at the cost of profound alterations of its physics, chemistry, ecology, and services. Here, we evaluate and compare the risks of impacts on marine and coastal ecosystems-and the goods and services they provide-for growing cumulative carbon emissions under two contrasting emissions scenarios. The current emissions trajectory would rapidly and significantly alter many ecosystems and the associated services on which humans heavily depend. A reduced emissions scenario-consistent with the Copenhagen Accord's goal of a global temperature increase of less than 2 degrees C-is much more favorable to the ocean but still substantially alters important marine ecosystems and associated goods and services. The management options to address ocean impacts narrow as the ocean warms and acidifies. Consequently, any new climate regime that fails to minimize ocean impacts would be incomplete and inadequate.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Gattuso, J-P -- Magnan, A -- Bille, R -- Cheung, W W L -- Howes, E L -- Joos, F -- Allemand, D -- Bopp, L -- Cooley, S R -- Eakin, C M -- Hoegh-Guldberg, O -- Kelly, R P -- Portner, H-O -- Rogers, A D -- Baxter, J M -- Laffoley, D -- Osborn, D -- Rankovic, A -- Rochette, J -- Sumaila, U R -- Treyer, S -- Turley, C -- New York, N.Y. -- Science. 2015 Jul 3;349(6243):aac4722. doi: 10.1126/science.aac4722.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Laboratoire d'Oceanographie de Villefranche, CNRS-Institut National des Sciences de l'Univers, F-06230 Villefranche-sur-mer, France.

    Description: Coral bleaching events threaten the sustainability of the Great Barrier Reef (GBR). Here we show that bleaching events of the past three decades have been mitigated by induced thermal tolerance of reef-building corals, and this protective mechanism is likely to be lost under near-future climate change scenarios. We show that 75% of past thermal stress events have been characterized by a temperature trajectory that subjects corals to a protective, sub-bleaching stress, before reaching temperatures that cause bleaching. Such conditions confer thermal tolerance, decreasing coral cell mortality and symbiont loss during bleaching by over 50%. We find that near-future increases in local temperature of as little as 0.5 degrees C result in this protective mechanism being lost, which may increase the rate of degradation of the GBR.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Ainsworth, Tracy D -- Heron, Scott F -- Ortiz, Juan Carlos -- Mumby, Peter J -- Grech, Alana -- Ogawa, Daisie -- Eakin, C Mark -- Leggat, William -- New York, N.Y. -- Science. 2016 Apr 15;352(6283):338-42. doi: 10.1126/science.aac7125.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Australian Research Council Centre of Excellence for Coral Reef Studies, James Cook University, Townsville 4810, Australia. ; Coral Reef Watch, U.S. National Oceanic and Atmospheric Administration (NOAA), College Park, MD 20740, USA.

    Notes: Abstract El Nifio related coral mortality and a subsequent increase in crustose coralline algae and sea urchins have resulted in profound changes to the coral reef ecosystem at Uva Island, Panama (Pacific coast). New data and a model are presented that analyze the CaCO3 budget of the reef. The model accounts for production by corals and coralline algae, erosion byDiadema, infauna, fish and other motile organisms, and the retention of sediments as a function of size. The 2.5 ha reef is currently eroding at an average rate of 4,800 kg/y or −0.19 kg/m2/y but there is tremendous variation among reef zones. While deposition in other zones range from +0.1 to 0.4 kg/m2/y, erosion of the seaward reef base averages about −3.65 kg/m2/y. The damselfish/algal lawn symbiosis protects portions of the reef framework, reducing net losses there by 2,000 kg/y (up to 0.33 kg/m2/y). Before the 1982-1983 El Niño, the overall reef was depositional. At that time, estimated production exceeded erosion in most zones, resulting in a net deposition of approximately 8,600 kg/y or 0.34 kg/m2/y.
