Securing Sustainable Somali Fisheries

By Peter Aronson, SRC intern Lots of people know about the issue of piracy in Somali waters in recent years, with mass coverage from American media and even Hollywood focusing on it with the 2013 movie Captain Phillips. However, many people don’t know that the loss of secure fisheries to illegal foreign vessels was the […]

The transfer of energy within a food chain: Why do large whales feed on small plankton?

By Meagan Ando, SRC intern The ten-percent rule toward energy transfer among levels of a trophic system is one that has been used to study ecosystems’ energy dynamics for a long time. But, in order to understand it, one must have a basic understanding of a food chain (Figure 1). Food chains describe the transfer […]

Loss of North American Freshwater Biodiversity

By Chris Schenker, SRC intern Despite garnering less attention than their marine counterparts, freshwater species are diverse, important, and also under threat. Despite covering only 0.8% of the world’s surface and accounting for about 0.01% of the world’s water, freshwater contains at least 100,000 distinct species (Dudgeon et al. 2006). Comparisons to other environments are […]

Permeable Pavement Systems as a Mitigation Strategy to Combat Stormwater Outfall and Sea Level Rise

By Casey Dresbach, SRC intern The EPA defines stormwater runoff as that which is generated from rain events that flow over land or impervious surfaces, such as paved streets, parking lots, and building rooftops, and does not soak into the ground (EPA, 2018). This accumulation of water ultimately ends up in coastal waters, but upon […]

A microscopic organism with a macroscopic impact: How climate change is affecting harmful algal blooms and what this means for future generations

By Carolyn Hamman, SRC intern Phytoplankton are photosynthetic microorganisms that exist in both marine and freshwater environments. There are several different types of phytoplankton each with their own unique preferred environmental parameters and strategies for growth. For example, some phytoplankton (called coccolithophores) use calcium to create protective plates they use as a defense mechanism (Beaufort […]

A Summary of Acoustic Tagging and Juvenile Salmon Acoustic Telemetry System Program in the Northwestern United States

By Brenna Bales, SRC intern Before the existence of satellite and acoustic tracking technologies, the most we knew about a certain marine species’ range was from either visual observations or catch data. By developing these systems and scientists cooperating globally by sharing their data, we have learned that some “tropical” species like tiger sharks are […]
