Volcanic Smog and Sunglint in the Vanuatu Archipelago
NASA – The Vanuatu Archipelago is a collection of volcanic islands about 1,800 kilometers (1,100 miles) northeast of Australia. Two of the islands, Gaua and Ambrym, frequently vent sulfurous gases.
On Jan. 7, 2014 NASA’s Aqua satellite passed over Vanuatu, allowing the Moderate Resolution Imaging Spectroradiometer (MODIS) aboard to capture this true-color image. A broad plume of volcanic vog and ash rises from Ambrym and spreads across the South Pacific. Vog is a combination of “volcanic” and “smog”, and is formed when gases from a volcano react with sunlight, oxygen and moisture.
The vog appears as a light blue-gray plume which arcs from the volcanic island both to the northwest and to the northeast. In the northeast, the vog crosses a mirror-like swath of silver-gray which runs from north to south. That swath is not volcanic in origin, but is an artifact called “sunglint” – the reflection of the sun off the ocean in a satellite image.

By Cindy Glass – What does it mean to take that awesome prototype into production? Step one: Pull out your cash-flow statement.
Here are nine considerations to make before taking your idea from prototype to production.
- BOM (Bill of Materials)
- MOQ (Minimum Order Quantity)
- PO (Purchase Order)
- Other fixed costs
If you are building a company around your product, other costs can creep up quickly: website, e-commerce site, merchant account, bookkeeper, workspace, trade shows, and so on. Most of these costs can’t be turned off easily when sales are slow. more> http://tinyurl.com/k5as2wb

By Megan McArdle – Overwork is not good for productivity.
If you’re doing physical labor, you get tired.
If you’re doing customer service, you get cranky.
If you’re sitting at a desk doing so-called knowledge work, you get stale and unimaginative.
Every time I come back from vacation, I dive back into work with new ideas and a lot more energy, and I think, “Why don’t I do this more often?” And still, every year, I lose most of my vacation days. more> http://tinyurl.com/ld8gf4v
