Weeds and Grass: mysterious and underappreciated treasures of the sea

Given the disdain for the word “weed,” it’s not surprising that seaweed gets such little respect in most developed human cultures. But, we are finding seaweed and its rooted cousin seagrass hold immeasurable value for the future of humankind. Time to get to work mapping it!

Seagrasses are considered vascular plants and have roots, stems, leaves, and flowers. According to a report from the United Nations in 2020, there are more than 70 species across the globe covering over 300,000 km2 (which is likely a vast underestimate) making them one of the most widespread coastal habitats.

Professional Spotlight – Dr. Chris Harrod and Chilean Kelp Mapping

Professional Spotlight

The Professional Spotlight series is a deep dive into the global BioBase community where we highlight the unique ways sonar driven mapping is assisting research, conservation and sustainability.

The BioBase team sat down with Dr. Chris Harrod for a look into how he uses BioBase. Chris (from the UK) is a full professor of Fish and Aquatic Ecology at the University of Antofagasta in Antofagasta, Chile. He does a mixture of research, teaching, and administration tasks but our interest with him was the applied research techniques for which he was using BioBase. His research is focused on a macroalgae called kelp (aka seaweed) and its importance as a source of food/energy to fish and invertebrates in the coastal zone. He is also interested in how kelp can function as habitat, food, an anchor of sediment and even slow the turbulent waters of the Pacific Ocean.
