Dr. Josh Kohut presented his current research at the March 20, 2014 STEM Educators’ Series. Dr. Kohut discussed his work on the interactions between the physical and biological worlds in the ocean, how climate change is influencing these interactions, and how using ocean observing data informs us about marine ecology. During the lecture, we shared activities related to biophysical interactions as well as discuss how to bring these topics into your classrooms/clubs.
Below we have included a summary of Dr. Kohut, Background Materials, the Lecture, and adapted activities to teach on the topics of biophysical interactions, marine ecology, and climate change science as we get closer to the event.
Enjoy! The East Coast MARE Team
Dr. Josh Kohut is an Assistant Professor at Rutgers University. He received his bachelor’s degree in Phsycis and Mathematics from the College of Charleston and completed his Ph.D. in Physical Oceanography at Rutgers University. His broad research interests are in bio-physical interactions in the world’s oceans, circulation processes on continental shelves, and the impact of these processes on marine resource management. I utilize ocean observing technologies including satellites, high-frequency radar, and underwater gliding robots as part of a research program that applies ocean observations to coastal research and decision making.
We have compiled the following materials as optional background information if you wish to read about the topics that will be covered during the event and included in the adapted lesson plans below (coming in March).

Activity 1 (Models Discussion): If we were going to develop a model to investigate biological and physical connections in the ocean, what variables would we need to include?
SEP 2: Developing and Using Models:
Activity 2 (Developing Explanations from online unit): Use evidence to construct an explanation that predicts and/or describes why fish migrate, which also includes the quantitative relationships between included variables.
We will begin the activity here (http://new.coolclassroom.org/adventures/explore/fish/19) on page 19 and continue through to page 22. You can follow along in the broadcast or do it yourself on your computer.
SEP 6: Constructing Explanations and Designing Solutions:
Activity 3 (Asking Questions from the Data): Using the data, is there a relationship between the variables? Develop a question to investigate the data further.
Temperature (degrees C): Fall 1993, Spring 1993, Fall 2002, Spring 2002
NOAA Fisheries Trawl Data (Catch Per Unit Effort): Fall 1993, Spring 1993, Fall 2002, Spring 2002
Temperature and Trawl Data: Fall 1993 .png, Spring 1993 .png, Fall 2002 .png, Spring 2002 .png; Fall 1993 .avi, Spring 1993 .avi, Fall 2002 .avi, Spring 2002 .avi
SEP 1: Asking Questions and Defining Problems:
Activity 4 (Data Interpretation): Use the maps to identify temporal and spatial relationships in phytoplankton along the Western Antarctic Peninsula.
Montes-Hugo et al. 2009 Data: Remote Sensing
Vemet et al. 2008: Ship Observations
SEP 4: Analyzing and Interpreting Data:
Activity 5 (Simulation & Analysis): Collect data through the simulation to serve as the basis for evidence to answer the question: what effects where predators forage?
