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 […]

Migration Dynamic of Juvenile Southern Bluefin Tuna

By: Julia Saltzman, SRC Intern Large-scale migrations are crucial to many different marine species. In southern bluefin tuna, this life history trait is critical for sustaining their valuable fisheries, and as such there are many scientific research programs designed to monitor the management of the species. Telemetry technology (remote tracking of spatial locations and movements) […]

The Utility of Combining Stable Isotope and Hormone Analyses for Marine Megafauna Research

By: Olivia Wigon, SRC Intern Marine megafauna face many threats such as ship strikes, climate change, ocean noise and habitat destruction, which have caused many populations to decline. Typically, conservation takes a reactive approach instead of a proactive one which makes it hard to maintain healthy populations of marine megafauna. Alyson H. Fleming and her […]

“Boo! Did we scare you?”: behavioral responses of reef-associated fish, prawn gobies (Amblyeleotris steinitzi and Amblyeleotris sungami) to anthropogenic diver disturbance 

By: Allison Banas, SRC Intern There are many factors that can affect the health of coral reef communities, SCUBA diving being one of them. Studies have shown that divers’ activities can have significant detrimental effects on the ecosystem, and this paper from Valerio et al. (2018) looks at the effect divers can have on the […]

Investigating the vulnerability of European Seafood Production to Climate Warming

By: Gaitlyn Malone, SRC Intern As the world’s climate continues to change, economic, social, and environmental changes will undoubtedly occur along with it. One sector that is expected to be economically affected by climate warming is seafood production (Breitburg et al., 2018). Seafood production, which includes both farmed and captured fish, shellfish, and seaweed in […]

Effectiveness of MPA’s

By: Peter Aronson, SRC Intern One might think that setting aside marine protected areas (MPA’s) – areas of the ocean where human activity is more heavily restricted – would reduce fishing pressure and overexploitation of marine species. However, that is not always the case. A group of researchers sought to determine if MPA’s experience intense […]

Are Polar Bears on Thin Ice?

By: Kaylie Anne Costa, SRC Intern When you think of polar bears what comes to mind? Is it a mama bear and a cub struggling to swim miles to find a piece of sea ice? Because that is exactly what is beginning to occur in the Arctic. With the rise of the sea surface temperatures, […]
