Resumen en español

Este ensayo revisa los alcances de la oceanografía social tal como fue presentada y discutida en la Primera Reunión de Oceanografía Social organizada en el Centro de Estudios en Geografía Humana de El Colegio de Michoacán en septiembre de 2017. La oceanografía social es un campo innovador e híbrido de estudio, situado en el umbral entre las ciencias naturales y sociales que abarca el estudio de las relaciones e interacciones de las sociedades humanas, presentes y pasadas, con el ambiente costero/marino. Dividimos el ensayo en dos secciones. Primero, describimos crono- lógicamente el surgimiento y evolución de la disciplina, así como un panorama contemporáneo del quehacer del oceanógrafo social y la imperante necesidad de expandir esta aproximación a todas las esferas de los estudios marinos. Finalmente, ofrecemos una síntesis de las fortalezas y retos que ofrece la oceanografía social y de cómo nos proponemos enfrentarlos a partir de la formación de un CoLaboratorio.

Resumen en inglés

This essay reviews the scope and aims of Social Oceanography as presented and discussed at the First Social Oceanography Meeting held at the Center for Human Geography Studies of El Colegio de Michoacán in September 2017. Social Oceanography is a hybrid field of study at the interface between the natural and social sciences focused on understanding the relationships and interactions of past and present human societies, and the coastal/marine environment. We present our argument in three sections. First, we describe the chronological development and evolution of the discipline. Second, we offer a contemporary overview of the sphere of action of social oceanographers and the pressing need to extend this approach to all spheres of marine studies. Lastly, we summarize the strengths and challenges of Social Oceanography and the ways we will deal with them through the creation of a CoLaboratory.

Resumen en inglés

Evaluating historical changes in the exploitation of marine organisms is a key challenge in fisheries ecology and marine conservation. In the Eastern Pacific, marine turtles were exploited for millennia before systematic monitoring began <50 years ago. Using ethnographic and historical data, we generated a detailed reconstruction of the East Pacific green sea turtle (Chelonia mydas) fishery in Mexico’s Baja California peninsula from 1700 to 1990. Sea turtles from the region’s important feeding areas were a staple food source from the earliest phases of human occupation, dating back at least 12,000 years. In contrast with regions such as the Caribbean, small human populations and limited market access resulted in apparently sustainable turtle harvests until the second half of the 20th century. We found that the estimated annual catches between 1960 and 1980 exceeded the estimated annual catches of the previous 250 years by an order of magnitude, leading to the collapse of the fishery and the depletion of the green turtle population. A total ban on sea turtle captures in 1990, comprehensive nesting beach protection, and significant conservation efforts resulted in increases in breeding females on nesting beaches and catch rates in scientific monitoring on main feeding grounds since the early 2000s. This provides a positive outlook for this once-depleted population segment. Although further research is needed to evaluate current conservation status, we have identified a date, between 1950 and 1960, which can serve as a reliable temporal reference for future evaluations of historical baseline abundance in this region.
