Science Lectures - 2017

Please join Point Reyes National Seashore staff for Science Lectures, 45 minute presentations on scientific research being performed at Point Reyes and elsewhere in the California. Science Lectures are sponsored by the Pacific Coast Science and Learning Center at Point Reyes National Seashore. They usually occur at noon on many Thursdays throughout the year and are normally held at the Red Barn Classroom at Point Reyes National Seashore's Headquarters. All are welcome and admission is free.

Visit our Science Lectures page to learn about upcoming lectures.

Some of our Brown Bag Lectures in 2017 included:

 
Water cascades down a short cliff from the left onto a wide sandy beach. Waves break on the right.

Date: Thursday, January 26, 2017
Title: "Sea cliff retreat and coastal waterfalls in Point Reyes"
Presenter: Patrick Limber, Ph.D., U.S. Geological Survey, Santa Cruz, CA
Summary: In California, nearly three-quarters of the coastline consists of eroding sea cliffs or bluffs. Cliff retreat often happens suddenly and without warning: wave impacts can undercut and destabilize sea cliffs, causing rapid collapse. Cliff collapse and retreat can be hazardous, but it also gives rise to spectacular coastal features such as sea stacks, arches, and coastal waterfalls.

In this talk, Patrick discussed: 1) historical and future cliff retreat hazards along the Point Reyes coastline; 2) the formation of erosional coastal features such as arches, caves, and sea stacks; and 3) how coastal waterfalls develop, like Alamere Falls in Point Reyes, and why they are uncommon geological features.

Eelgrass (a "seaweed") is visible below the water's surface. Vegetation covers the shoreline in the background.

Date: Thursday, March 2, 2017
Title: "The Eelgrass Microbiome"
Presenter: Melissa Kardish, Ph.D. Candidate at UC Davis
Summary: Melissa Kardish will discuss the diversity of the bacterial communities on eelgrass. She is incorporating data on the diversity of these communities from around the world—including from samples in Tomales Bay—to look at patterns in these communities and how they vary with invertebrates, host plants, and environmental conditions. She is a graduate student at UC Davis working with the Seagrass Microbiome Project and the Zostera Experimental Network.
