How to Solve 5 Common Discrete Water Sampling Challenges

It’s with great pleasure that I’m hosting this month’s webinar on February 28th about some of the most common discrete data management challenges. This topic comes up repeatedly in the field of environmental data management. Regardless of the size of your organization, I’m sure some of the challenges that we’re going to outline will resonate with you and your colleagues.

Protecting Endangered Species with Continuous Water Quality Data

Better Water Management of Critical Habitat for Endangered Species

In the United States, the Endangered Species Act of 1973 (ESA) defines endangered species as “any species which is in danger of extinction throughout all or a significant portion of its range… “ and critical habitat as “the specific areas within the geographical area occupied by the species … on which are found those physical or biological features (I) essential to the conservation of the species and (II) which may require special management considerations or protection.” However, when the Endangered Species Act talks about conservation it refers to instruments such as: “research, census, law enforcement, habitat acquisition and maintenance, propagation, live trapping, and transplantation …” Those instruments may have been the best available at the time but times have changed.

A Question of Scale: Reconciling Point-Scale Observations With Watershed-Scale Outcomes

Laboratory analysis of a water quality sample links a lot of data and metadata to a singular point in time and space. However, the objectives for monitoring may span spatial and temporal scales from point sampling (e.g. at an outfall) to watershed assessment (e.g. to characterize waters; identify trends; assess threats; inform pollution control; guide environmental emergency response; and support the development, implementation, and assessment of policies and regulations). Reconciling data- and metadata-dense analytical results with watershed-scale outcomes is a work-in-progress for many monitoring agencies.

The GLOS Data Challenge Helps Solve Water Problems in the Great Lakes

The Great Lakes hold 21% of the world’s fresh surface water by volume. Only the right information today can ensure the sustainable use of these waters for generations to come. In North America, the Great Lakes account for 84 percent of fresh surface water. Today, these lakes are sourced for drinking water for over 40 million people. One and a half million U.S. jobs and $62 billion in U.S. wages depend on the health of the Great Lakes. While restorations efforts are progressing, climate change and water quality concerns still threaten their ecosystem. You’re invited to make a difference by participating in the 2016 Great Lakes Observing System (GLOS) Data Challenge!

Game Changers – Continuous Water Quality Monitoring

Surrounded by hydrologists on a day-to-day basis, I most certainly talk about discharge and rating curves a lot. I find discussions about hydrometrics fascinating (actually I find any discussions about water and data management inspiring, but that is a whole other issue). But alas, I’m a self-professed “Water Quality Nerd” and a Water Quality Professional by trade.

2014 NWQMC Takeaway – The Industry is Moving to Continuous Monitoring

Day 2 of the National Water Quality Monitoring Conference in Cincinnati, OH was an interesting day of presentations. The rest of the week appears to be just as fascinating. It has been great reconnecting with old peers, making new connections, and listening to the presentations on some very thought-provoking projects. The passion for water resources…

Monitoring Needed as “Science” Endorses the Keystone XL Pipeline

In a bold move, Marcia McNutt, the Editor-in-Chief of Science Magazine, one of the world’s top scientific journals, endorsed the Keystone XL pipeline late February1. The controversial pipeline, designed to transport heavy crude from Canada’s oil sands to US Gulf coast refiners, has been mired in controversy over its potential ecological and climate impacts. McNutt,…

Neil Young & The World Bank – Water vs Energy

The recent uproar over Neil Young’s comments about Alberta’s oilsands development got me thinking about energy and water. Water is used in many of our energy generation methods. Whether it’s hydro power, thermal generation, oil extraction, etc., water is vital to most current energy production methods. That might not be a problem except water is…

Soothing a Sting to the Integrity of Science

Scientific knowledge shapes many of our collective beliefs and decisions, but what of its integrity? It’s a question that’s receiving increasing attention, most recently because of a strategically orchestrated sting operation by Science Magazine’s John Bohannon involving the submission of intentionally flawed papers to over 300 open-access journals 1.  It revealed a less than pretty…
