Australia's Coral Sea - How Much Do We Know?
Proceedings of the 12 th International Coral Reef Symposium, Cairns, Australia, 9-13 July 2012 18E The management of the Coral Sea reefs and sea mounts Australia's Coral Sea - how much do we know? Daniela M. Ceccarelli 1 1PO Box 215, Magnetic Island QLD 4819 Australia Corresponding author: [email protected] Abstract. Recent efforts to implement management zoning to Australia’s portion of the Coral Sea have highlighted the need for a synthesis of information about the area’s physical structure, oceanography and ecology. Current knowledge is hampered by large geographic and temporal gaps in existing research, but nevertheless underpins the determination of areas of ecological value and conservation significance. This review draws together existing research on the Coral Sea’s coral reefs and seamounts and evaluates their potential function at a regional scale. Only four coral reefs, out of a potential 36, have been studied to the point of providing information at a community level; this information exists for none of the 14 mapped seamounts. However, the research volume has increased exponentially in the last decade, allowing a more general analysis of likely patterns and processes. Clear habitat associations are emerging and each new study adds to the’ Coral Sea species list’. Broader research suggests that the reefs and seamounts serve as dispersal stepping stones, potential refugia from disturbances and aggregation hotspots for pelagic predators. Key words: Isolated reefs, Dispersal, Community structure, Refugia. Introduction Australia’s Coral Sea lies to the east of the Great Barrier Reef (GBR) within the Australian EEZ boundaries. Geologically, it is dominated by large plateaux that rise from the abyssal plain and cover approximately half of the seabed area (Harris et al. -
The Science Behind Volcanoes
The Science Behind Volcanoes A volcano is an opening, or rupture, in a planet's surface or crust, which allows hot magma, volcanic ash and gases to escape from the magma chamber below the surface. Volcanoes are generally found where tectonic plates are diverging or converging. A mid-oceanic ridge, for example the Mid-Atlantic Ridge, has examples of volcanoes caused by divergent tectonic plates pulling apart; the Pacific Ring of Fire has examples of volcanoes caused by convergent tectonic plates coming together. By contrast, volcanoes are usually not created where two tectonic plates slide past one another. Volcanoes can also form where there is stretching and thinning of the Earth's crust in the interiors of plates, e.g., in the East African Rift, the Wells Gray-Clearwater volcanic field and the Rio Grande Rift in North America. This type of volcanism falls under the umbrella of "Plate hypothesis" volcanism. Volcanism away from plate boundaries has also been explained as mantle plumes. These so- called "hotspots", for example Hawaii, are postulated to arise from upwelling diapirs with magma from the core–mantle boundary, 3,000 km deep in the Earth. Erupting volcanoes can pose many hazards, not only in the immediate vicinity of the eruption. Volcanic ash can be a threat to aircraft, in particular those with jet engines where ash particles can be melted by the high operating temperature. Large eruptions can affect temperature as ash and droplets of sulfuric acid obscure the sun and cool the Earth's lower atmosphere or troposphere; however, they also absorb heat radiated up from the Earth, thereby warming the stratosphere. -

Lava Layering Purpose to Learn About the Stratigraphy of Lava Flows Produced by Multiple Eruptions
Teacher Page Lava Layering Purpose To learn about the stratigraphy of lava flows produced by multiple eruptions. Background [also see “Teacher's Guide” Pages 3, 4, 12, 13] Dark, flat maria (layers of basaltic lava flows) cover about 16 percent of the Moon’s total surface. They are easily seen on a full Moon with the naked eye on clear nights from most backyards. The maria, quite similar to Earth’s basalts, generally flowed long dis- tances utlimately flooding low-lying areas such as impact basins. Yet, the eruption sources for most of the lunar lava flows are difficult to identify. The difficulty in finding source areas results from burial by younger flows and/or erosion from meteor- itic bombardment. Generally, the overall slope of the surface, local topographic relief (small cliffs and depressions), and eruption direction influence the path of lava flows. Detailed maps of the geology of the Moon from photographs reveal areas of complicated lava layering. The study of rock layering is called stratigraphy. On the Moon, older flows become covered by younger flows and/or become more pocked with impact craters. On Earth, older lava flows tend to be more weathered (broken) and may have more vegetation than younger flows. Field geologists use differences in roughness, color, and chemistry to further differentiate between lava flows. They also follow the flow mar- gins, channels, and levees to try to trace lava flows back to the source area. The focus of this activity is on the patterns of lava flows produced by multiple erup- tions. We use a short cup to hold the baking soda because we are looking at the flows and not at constructing a volcano model. -
Pacific Reef Assessment and Monitoring Program Benthic Monitoring Summary: American Sāmoa 2015
Pacific Reef Assessment and Monitoring Program Benthic monitoring summary: American Sāmoa 2015 About this summary The purpose of this document is to provide a brief summary of the most recent survey efforts conducted in the islands of American Sāmoa by the Coral Reef Ecosystem Division (CRED) of the NOAA Pacific Islands Fisheries Science Center as part of the Pacific Reef Assessment and Monitoring Program (Pacific RAMP). A more detailed assessment of coral populations and reef community structure in American Sāmoa will be summarized in a forthcoming annual report. Sampling effort - Ecological monitoring in American Sāmoa was conducted from February 15 – March 30, 2015. Figure 2. Mean density of all juvenile coral colonies (Scleractinia, < 5 cm) at survey sites. - Surveys were conducted at 188 sites across 5 islands and atolls: Ofu-Olosega, Rose, Swains, Ta‘ū, and Tutuila. - Coral demography, partial mortality, and condition were surveyed using belt transects; benthic community structure will be assessed using photoquadrats. Overview of data collected Figure 3. Mean density of adult (dark) and juvenile (light) coral colonies (± standard error) grouped by island within three depth categories: shallow (0–6 m), mid (>6–18 m), and deep (>18–30 m). Figure 1. Mean density of all adult coral colonies (Scleractinia, ≥ 5 cm) at survey sites. Overview of data collected (cont.) colonies measured, two colonies were identified as Pavona diffluens and 813 colonies identified as Isopora sp. The threatened species Isopora crateriformis was not consistently identified to species throughout our survey efforts in American Samoa due to the similarity to I. cuneata when both have an encrusting morphology. -
