BatteryBench: A Protocol for Testing Portable Battery Chargers and Electronic Devices for Backpacking
Backpacking Light, December 2021

Some backpackers use a portable battery charger to keep other battery-powered devices running on longer trips. Portable battery chargers are also known as portable battery packs, battery banks, battery packs, portable chargers, portable power devices, portable power banks, power banks, or power packs.

It’s almost too easy to find tests and comparisons of portable battery chargers. But none that I read or watched focused on the most important factors that backpackers should care about, including the lightest models for charging your phone or earbuds.



Adapting to Changing Wildfires: Part Three
Backpacking Light, November 2020

This past summer and fall, wildfires in the Western U.S. seemed to set new records daily. News reports featured endless streams of scary images, incomprehensible statistics, and mysterious maps. But all of this told only part of the story.

NASA satellites with special infrared sensors capture images of fires every day. By animating those images, we can get a different look at how fast and how far wildfires grew in 2020.



Adapting to Changing Wildfires: Part Two
Backpacking Light, October 2020

Wildfires in western North America have changed for the worse and will continue changing. Fire tornadoes ripped living trees out of the ground, set them alight, and dropped them miles away. Blazes consumed 400 square miles (1,000 square km) in one day. Researchers compared the worst wildfires to the firebombing of Dresden in World War II or Hiroshima’s destruction by an atomic bomb.

While reasonably cautious backpackers are unlikely to perish in wildfires, we must learn to live with altered fire behavior, landscapes, and rules. This essay is an exploration of what some of those changes might look like.



Adapting to Changing Wildfires: Part One
Backpacking Light, October 2020
Chart of US Wildfire Area Per Year, comparing 1926-1945 to 2000-2109
What is the future of backpacking in an era of frequent massive wildfires? This year’s giant blazes in the Western U.S. closed many thousands of square miles (tens of thousands of square kilometers) in forests and parks for weeks and months. This essay gives you some background on wildfires in the U.S., describes the potential health and safety risks, and suggests how to stay safer and healthier.



USGS Science in Point Reyes National Seashore
USGS, December 2016

The park also uses USGS science to manage this iconic but complex setting. For example, local ranchers lease 28,000 acres of National Park land for dairy and beef cattle. To monitor ranch lands, the park uses maps, air photos and other databases from USGS.



Condors in Purgatory
Science Notes, August 2015, multimedia

Chart showing one carcass out of 200 containing a lead bullet puts 85 percent of condors at risk
Swooping low across a canyon inside Pinnacles National Park, California condor #444 appeared to be in fine health. “Ventana” hatched in 2007 from a nest in Big Sur, and she paired five years later with #340. The next year they fed their first chick regurgitated food scavenged from miles away. That food came from a dead animal—rotting, stinking and crawling with maggots. But one of the condor’s favorite meals, the gut pile left behind after a hunter kills a deer or wild pig, threatens the survival of this critically endangered species.

Rising Seas and Storms Could Seriously Damage California’s Coast within 30 Years
Sound Waves, March 2019
Chart comparing California coastal flood risk: $10 billion damage from 1989 Loma Prieta Earthquake, $32 billion from 2040s Sea-Level Rise + Exterme Storms, $127 billion from 2005 Hurricane Katrina, and $150 from 2100 Sea-Level Rise + Extreme Storms
In less than 30 years the combination of 10 inches of sea-level rise plus an extreme storm along California’s coast could flood more than 150,000 residents and impact over $30 billion in property value. By 2100, when the oceans could be 6.6 feet higher, up to 600,000 people and $150 billion in property could be at risk from coastal flooding—potentially worse than Hurricane Katrina in destruction.

Giant Grooves Discovered on an Earthquake Fault Offshore Costa Rica
Sound Waves, February 2018
Oblique sonar image showing giant grooves on the seafloor
Imagine dragging your outstretched fingers through wet beach sand, leaving long grooves behind. Scientists recently discovered similar but enormous grooves buried under the seafloor near Costa Rica. The detailed three-dimensional data they used to uncover these corrugations can help them better understand large subduction zone earthquakes and related tsunamis worldwide.

If the data you need still exists ...

Data management was an important part of my job for several decades. In 2012, while working for the U.S. Geological Survey (USGS) in Santa Cruz, California, I wrote this email and sent it to one coworker:
From: Rex Sanders <rsanders@usgs.gov>
Subject: Re: DM Quote
Date: July 23, 2012 at 4:52:42 PM PDT

Belated thanks. Quote's been percolating in my idea factory.

Here's a restatement:

If the data you need still exists …
If you found the data you need …
If you understand the data you found …
If you trust the data you understand …
If you can use the data you trust …
Someone did a good job of data management.

I prefer more positive statements.

Excellent science depends on excellent data management.
