Election Forum - Whatcom County Jail Tax

Jails are very much a part of the Washington landscape (had to get that in). Every county in the state has one as do many of the cities. The county jail is the leading edge of the United States criminal justice system. The jail is a big part of every County budget. Criminal justice and criminal justice spending is complex.

Wildfires kill 43 in Portugal.

Sciency Thoughts | 21 October, 2017
Forty three people have been confirmed dead and a further 71 have been injured as a series of wildfires have swept across northern and central Portugal this week. The majority of those who have died have done so in their cars, trying to escape from raging forest fires on country roads. Over 600 separate fires have been reported, the second major outbreak of such fires this year, after a series of fires in June killed 64 people and injured over 250 more in the central Pedrogao Grande Region. At least four people have died in similar fires in neighbouring Spain this week.

Fireball over Long Island, New York.

Sciency Thoughts | 21 October, 2017
The American Meteor Society has received reports of a bright fireball meteor being seen over Long Island, New York, at about 3.00 pm, Eastern Daylight Time (about 7.00 pm GMT), on Wednesday 18 October 2017. The majority of the sightings came from New York and New Jersey, though reports have come from Connecticut, Delaware, Rhode Island, Pennsylvania, Massachusetts, Maryland and New Hampshire as well. A fireball is defined as a meteor (shooting star) brighter than the planet Venus. These are typically caused by pieces of rock burning up in the atmosphere, but can be the result of man-made space-junk burning up on re-entry.

Eurypeza aurora: A new species of Scarab Beetle from Nairobi, Kenya.

Sciency Thoughts | 21 October, 2017
Scarab Beetles, Scarabeidae, are a large and diverse group, containing about 30 000 known species from around the world. These Beetles are typically large and robust, and often with a metallic colouration. Many Scarab Beetles are excellent diggers, and many of these digging Scarabs share a habit of burying their eggs with a supply of dung to feed their young, gaining them the name Dung Beetles, though others lay their eggs on carrion, decaying plant matter, or in some cases living plants.

Bacterial infection kills 125 000 Salmon at Scottish Fish farms.

Sciency Thoughts | 21 October, 2017
Around 125 000 Salmon have died following an outbreak of the Bacterium Pasteurella skyensis at two Fish farms in Loch Erisort on the island of Lewis in the Outer Hebrides, off the west coast of Scotland since August 2017. The outbreak has claimed the lives of about 500 tonnes of Fish at the Marine Harvest operated farms, prompting complaints from local residents about the scent of decaying Fish.

ExoMars aerobraking becomes too severe; shifts automatically to higher orbit

ExoMars has successfully performed a Flux Reduction Manoeuvre (FRM) for the first time. The manoeuvre was triggered by the excessive density of Mars' atmosphere, which had slowed the spacecraft above the limit the operations team normally allows. T...

Safety at Sea

Notes from the field | 20 October, 2017
One of the issues that is never far from one's thoughts on a ship is preparation for emergencies.  We are a long way from first responders or help of any kind. Therefore, crew and passengers (us scientists) need to be prepared to help ourselves and our mates. This blog is meant to reassure those ashore that your friends and family on Revelle are safety conscious and prepared for emergencies.

GeoTalk: Hellishly hot period contributed to one of the most catastrophic mass extinctions of Earth’s history

EGU Geolog | 20 October, 2017
Geotalk is a regular feature highlighting early career researchers and their work. Following the EGU General Assembly, we spoke to Yadong Sun, the winner of a 2017 Arne Richter Award for Outstanding Early Career Scientists, about his work on understanding mass-extinctions. Using a unique combination of sedimentological, palaeontological and geochemical techniques Yadong was able to identify some of the causes of the end-Permian mass extinction, which saw the most catastrophic diversity loss of the Phanerozoic.

Can't See the Forest for the Creek; Or is it the Other Way Around? California's Mega-droughts

Geotripper | 20 October, 2017
The eastern Sierra Nevada is home to one of the strangest forests I know of. It's not the species of tree that is odd; they are mostly Ponderosa, a pretty but unremarkable tree which can also be found on the adjacent slopes. What's strange is that th...

Wooster’s Fossils of the Week: Foraminifera clustered around a sponge boring (Campanian of southwestern France)

Wooster Geologists | 20 October, 2017
If all goes to plan, today I leave for the Annual Meeting of the Geological Society of America, held this year in Seattle, Washington. To mark the occasion, this week's fossil is from a poster Macy Conrad ('18), Paul Taylor (Natural History Museum, London) and I are presenting on Tuesday at the meeting. It comes from our delightful work in southwestern France this summer. There we explored the Type Campanian (Upper Cretaceous) and collected bucketfuls of the oyster Pycnodonte vesicularis. We've been studying the sclerobionts on these oysters ever since.

Magnitude 4.8 Earthquake off the coast of Nicaragua.

Sciency Thoughts | 19 October, 2017
The United States Geological Survey recorded a Magnitude  4.8 Earthquake at a depth of 76.5 km, about 25 km offshore of the Padre Ramos estuary on the coast of Chinandega Department, Nicaragua, slightly after 5.00 pm local time (slightly after 11.00 pm GMT) on Tuesday 17 October 2017. There are no reports of any damage or casualties associated with this event, though it was felt in Nicaragua and El Salvador.
