Queensland sinkhole linked to submarine landslide.

Sciency Thoughts | 26 November, 2015
Swimmers and surfers have been advised to keep away from an area of Jumpinpin Beach on North Stradbroke Island, to the south of Brisbane in Queensland, Australia, after a section of beach approximately 100 m long disappeared abruptly on Wednesday 25 November 2015. Nobody was hurt in the incident, and nor was it directly observed, due to the remoteness of the beach, about 15 km from the nearest patrolled beach, however the event has changed the flow of currents in the area in unpredictable ways and the sand on the beach close to the gap is described as being 'unstable'.

Highlights—The Rise and Fall of Lakes

JSR Paper Clips | 26 November, 2015
Rapid tectonic and climate changes can markedly influence lake extent and character, with distinct expression along- and across-strike. Ghinassi et al.suggest that although the morphological along-strike variability of lacustrine coasts is relatively well understood, the nature and signature of this variability on the sedimentological and stratigraphic record of lacustrine systems is poorly documented. This study documents how lacustrine water-level oscillations are recorded in different depositional systems along strike in late Holocene shoreline deposits of Lake Hayk of Ethiopia. The results illustrate low-relief margins with fluvial-deltaic systems and high-relief margins with collvial fan deltas and stromatolitic biostromes. The data reveal possible pitfalls of classical stratigraphic approaches used to establish along-strike correlation between lacustrine sedimentary successions, important for paleoenvironmental studies, subsurface exploration and stratigraphic investigations.

Symposium on former gasworks in Ghent...by Darren Beriro

The 6th International Symposium on Manufactured Gas Plant Sites (MGP 2015) held in the historical city of Ghent, Belgium, was a great success, with 150 delegates and speakers from five continents. The symposium was attended by consultants, remediation contractors, environmental regulators and site owners, making it both practical and appliedPanoramic photo of Ghent old town taken from the famous Belfry The relevance of MGP 2015 to BGS is the discussion around contaminated soil and groundwater present at former gasworks. Conferences like MGP 2015 play an important part in the regeneration and redevelopment of gasworks. This links directly to UK government policies on reuse of brownfields, facilitation of housing and the protection of human health from environmental pollution. The contaminants present at former gasworks are dominated by hydrocarbons, including polycyclic aromatic hydrocarbons (PAH). This is because the process used to produce the gas relies on the heating of coal (or similar fossil fuel) to high temperatures in a low oxygen environment, resulting in a number of by-products, residuals and wastes including coal tar.  These mainly organic chemicals are complex and are known to be hazardous to human health.

A volcano lovers gift guide

The Volcano Diaries | 26 November, 2015
Once again, it is that time of the year - when the smell of baked goods and mulled wine floats through the air, jingly music comes from a speaker somewhere, and you can hear the crackling of a fire and the roar of a volcano... uh, what?Just as to any volcano lover, volcano-y gifts are the icing on the holiday cake to me. So I thought I'd put together a list of awesome volcano-related gift ideas*, and share them with you. If you're not interested in gifts, but would like the take a super quick survey about science blogging, go ahead and scroll to the end.

A radar scientist’s day in the field: At NPOL during OLYMPEX

Notes from the field | 26 November, 2015
The western side of the Olympic Mountains are a sight to behold, with crashing waves along the rocky coasts and mossy trees in the rain forest signifying the impressive amounts of precipitation that falls in this area. The ongoing Olympic Mountains Experiment (OLYMPEX) is set up to measure rain and snow over the oceans up to the highest mountain peaks using airborne and ground-based instruments. As part of this project, NASA's ground-based weather radar, NPOL, sits atop a hill on the Quinault Indian Reservation, with clear views out over the ocean and up the Quinault valley toward the snowy mountains.

A grim forecast for Colorado River Basin ag under climate change

Inkstain (John Fleck) | 26 November, 2015
Surface-water supply reductions (relative to current agricultural surface-water use) range from 20 percent to more than 75 percent across areas of the Mountain, Pacific, and Plains regions in 2080. The most severe declines occur in the middle and lower Colorado River Basin under virtually all scenarios, while other river systems with headwaters in the central Rocky Mountains and Sierra Nevada range are affected to varying degrees depending on the scenario. In general, surface-water supply impacts for irrigated agriculture under climate change are increasingly severe over time, with the most significant impacts occurring after 2050. These reductions are calculated based on climate conditions averaged over a 20-year window; they do not reflect the magnitude of supply reduction that could occur under multiyear drought conditions.

Wishes for a Happy Thanksgiving, and Safety for Those on the Road

Geotripper | 26 November, 2015
Here's hoping that you all have a fine Thanksgiving holiday and that your travels are safe and fun. I offer up one of the things that I am truly thankful for: politicians that put aside their many differences and agreed to establish Pinnacles National Park in 2013. Maybe we can all learn something from the shock of actually working together and compromising: Democrats, at dinner this week be kind to your Republican relatives, and Republican relatives, be kind back. Be thankful that we can still argue politics without fear of reprisals.

Living the Dream, Day 3 – Ruins and the Redwall

Watch for Rocks | 25 November, 2015
I awaken slowly in the spring dawn and stretch inside my sleeping bag, feeling stiff and brittle as a sun-bleached boat paddle. Footsteps crunch gently across the sandy beach. Softly muffled chatter grows louder, pots and pans clang more frequently as our guides begin breakfast preparations at their lavish camp kitchen. It is time to extricate myself from my ground-dwelling nest. The coffee gong sounds brash and heavenly. It is the morning of our first full day on the Colorado River in Grand Canyon; on hands and knees I crawl out of my already sandy tent and shake myself awake, keen to continue the adventure. Just throw me in the river and I will limber up in no time.

Two people have been confirmed dead following an Earthquake in Badakhshan Province in north-eastern Afghanistan on Sunday 22 November 2015. The quake was measured as having a Magnitude of 5.9 and occurring at a depth of 92 km by the  United States Geological Survey and was felt as far away as West Bengal in India.
