Seaweeds (macroalgae) represent the most striking living components in the Antarctic?s near-shore ecosystems, especially across the West Antarctic Peninsula and adjacent islands. Due to their abundance, their central roles as primary producers and foundation organisms, and as sources of diverse metabolically active products, seaweed assemblages are fundamental to biogeochemical cycles in Antarctic coastal systems. In recent years, the imminence of climate change and the direct impacts of human beings, which are affecting vast regions of the Antarctic, have highlighted the importance of seaweed processes in connection with biodiversity, adaptation and interactions in the benthic network.

Various research groups have been actively involved in the investigation of these topics. Many of these research efforts have a long tradition, while some ?newcomers? have also recently contributed important new approaches to the study of these organisms, benefiting polar science asa whole. This book provides an overview of recent advances and insights gleaned over the past several years. Focusing on a timely topic and extremely valuable resource, it assesses the challenges and outlines future directions in the study of Antarctic seaweeds.

Iván Gómez

Currently a Full Professor at the Instituto de Ciencias Marinas y Limnológicas, Universidad Austral de Chile and Deputy Director of the Fondap Research Center Dynamic of High Latitude Marine Ecosystems (IDEAL). In 1991, Prof. Gómez completed his bachelor and MSci studies at the Universidad Austral de Chile in Valdivia. In 1993 he was awarded a DAAD fellowship to continue his PhD studies at the Alfred Wegener Institute for Polar and Marine Research and the University of Bremen, Germany. He subsequently pursued postdoctoral research at the Universidad de Malaga, Spain and the Alfred Wegener Institute, prior to being appointed at the Universidad Austral de Chile in 2002. Prof. Gómez has considerable experience in the coordination of diverse research projects focused on the ecology, photobiology and physiology of seaweeds from different coastal systems, including cold-temperate and polar regions. He has participated in 11 campaigns inthe Antarctic. He recently published the book “Flora Marina Antártica: Patrimonio de Biodiversidad,” which condenses the work of many years in a format accessible to a general audience.
