Joint Aquatic Sciences Meeting Brings FlowCam Users Together to Share Research

In May 2022 our FlowCam Aquatic Team attended the Joint Aquatic Sciences Meeting (JASM) in Grand Rapids, Michigan. This historic meeting brought together scientists from nine different societies to form the largest gathering of its kind in history. It was a welcome change after two years of virtual meetings and limited in-person collaboration.

Water Quality Monitoring Workshop to be Offered at AWWA ACE Conference

After a two-year break, the American Water Works Association's ACE Conference will be hosted in-person in San Antonio, Texas, from June 12th - 15th. The conference brings together water sector professionals from around the country to learn about new technologies and techniques in water quality monitoring, mitigation strategies, and overcoming engineering challenges.

FjordFlux Cruise Uses FlowCam to Analyze Glacier Particles and Assess Effects of Climate Change

FlowCam user, Jochen Wollschläger, of Germany's University of Oldenburg, recently returned from a research trip aboard the RV METEOR as part of the FjordFlux Cruise in the Beagle Channel, at the southernmost tip of Chile and Argentina. The goal of the expedition was to utilize the fjords of Patagonia to better understand how climate change will affect similar environments in Antarctica. Carried out in the context of the DYNAMO Project, the cruise was a cooperation between Germany, Chile, and Argentina.

FlowCam Measures Size of Zooplankton in China's Three Gorges Reservoir

Zooplankton are an essential part of the aquatic food web. They are the thread that connects the primary producers (phytoplankton) to high trophic organisms, and due to their small size are easily affected by changes in their environment. This makes them a good indicator of water quality and the effects of climate change on the health of water systems.

The Xiangxi Bay of the Three Gorges Reservoir in the Yichang region of China recently served as a place to observe these effects. The bay exhibits high spatial heterogeneity (or an uneven concentration of zooplankton species between different areas of the reservoir). It is this characteristic, likely resulting from variable nutrient levels, that made it a good place to study differences in zooplankton size spectrum and diversity as they relate to environmental factors.

Preventing Embolism from Medical Implants by Using FlowCam Imaging Particle Analysis

In a recent paper from Rostock University Medical Center, authors Anja Kurzhals et al. summarize a study they performed to determine the relevant morphological characteristics of particulates shed by a commercially available coronary stent delivery system. Flow Imaging Microscopy (FIM), also called Dynamic Image Analysis (DIA), was used to image and analyze particles produced during a simulated implantation of the cardiovascular device.

FlowCam Customer Methodologies to be Presented at the 2nd Annual Virtual Harmful Algal Bloom Research Symposium

In early January, the Algal Bloom Action Team, a collaboration of water professionals, researchers, and educators from twelve states in the North Central Region of the United States is hosting its 2nd annual Virtual Harmful Algal Bloom Research Symposium. Team members include the national network of Water Resources Research Institutes (WRRI), the North Central Region Water Network, and university extensions within each state in the North Central Region. The free-to-attend symposium will bring together researchers from across the US to present and discuss the latest developments in HAB research and outreach. Presentations will cover four different topics:

  • HAB Monitoring and Ecology
  • Cyanotoxin Treatment and Detection
  • Forecasting and Modeling HABs
  • Emerging Technology for Detecting and Monitoring HABs

Confederated Tribes of Coos, Lower Umpqua, and Siuslaw Indians Integrate FlowCam into Environmental Stewardship Programs

The Confederated Tribes of Coos, Lower Umpqua, and Siuslaw Indians (CTCLUSI) recently received long-awaited funding to purchase a FlowCam Cyano instrument, after first learning about FlowCam at an east coast workshop a few years ago. CTCLUSI makes up three tribes (4 bands) who all reside in close proximity to one another along the Coos River Tributaries in Oregon. According to the CTCLUSI website:

Community Groups Take HAB Monitoring Into Their Own Hands, Recognize Need for Formal Strategic Guidelines

Harmful algal blooms can have a detrimental effect on the environment and on human and animal health. As a result of climate change, water utilities are experiencing these events with increasing frequency. Historically, many water monitoring agencies have not had a plan in place to proactively monitor for cyanobacteria, but rather found themselves reacting to the effects of a bloom after the fact.

Last month, the US EPA released a report that addresses concerns within the agency about the lack of a cohesive, agency-wide plan to monitor freshwater bodies for harmful algal blooms (HABs):
