Tidal currents boil and swirl around the study site and safety is top priority. A sharp look out for sneaker waves keeps everyone dry.

The first job is to stretch out a reference tape measure.

Using ancient but precise, Egyptian technology, the students carefully measure vertical height using a water level and record the abundance of different species as they work their way up the shore.

The students are learning about marine ecology by doing it.

Getting up close and personal with limpets and periwinkles is the best way to make observations.

Direct observations help the students understand broader topics in marine science.

These little brooding anemones may not have a brain but they are sensible enough to "hang on" to their offspring and give them a head start over their 'cousins' with planktonic larvae.

These ancient mollusks haven't changed much in several hundred millions years. That is because they are well adapted to hang on to the rock and scrape off the algae using a metal scraper (aka a radula with iron in it).

These little aggregating anemones host algae in their skin, akin to the corals but soft. That is cooperation at its best.

Students work together to try and figure out the biotic and abiotic interactions that are shaping the the distribution of organisms.

Now comes the hard part of processing the raw data, pooling data and making sense out of the findings.

measuring biodiv2
Measuring marine biodiversity is the task today. Teamwork prevails. Many countries, cultures and languages unite to get a handle on species richness and the distribution of individuals across taxa.
