Organized by Centro Interdisciplinario de Ciencias Marinas-Instituto Politécnico Nacional and Instituto de Ciencias del Mar y Limnología–
Universidad Nacional Autónoma e México, November 18–20, 2020 (8:00- 16:00 h, duration may change depending of number of people participating during the web workshop).
The Gulf of California had experienced a long period 2014–2020 of anomalous warm sea surface conditions and decreasing sea surface chlorophyll-a concentrations compared with 2000–2013 period. The implications of such anomalous conditions on different ecosystems of the gulf remains basically unknown at this time scale.
A 3-days workshop is proposed to discuss and understand the influence of such anomalies in the marine ecosystems of the Gulf of California to respond the question
whether the Gulf of California is experiencing a decrease in biomass or productivity linked with climate variability? We invite students and researchers to show and discuss research related to response of biota to these unprecedent climatic conditions in an integrative perspective during a Web Workshop using System Zoom. There will be Oral online presentations of 30 minutes (including questions) from the audience and also it will be Electronic posters that will be permanently hosted in a web served for reading during conference with possibility to interact with the authors via distinct zoom accounts during a period specifically assigned for poster discussion (2 h each day of the workshop). No application fee is required for application and will be provided an official letter of participation for people presenting Oral or online poster, as well as official letter of participation for people that participate in the discussion of the meeting. Each person can be first author of maximum two works, one oral and another one poster. Our goal is to link the observed from remote satellite sensing and in situ measurements to a broad areas and knowledge of biological, ecological and oceanographic processes of the Gulf of California.
Topics to be discussed (but not limited to) Biodiversity and productivity
Studies that quantify biodiversity and productivity in distinct ecosystems in the Gulf of California
Plankton, benthos and/or nekton ecology associated with climatic change Ecological studies that quantify changes in species composition, abundance and biomass in time and space as a function of climatic change
Health ecosystem and food security (fisheries and conservation)
Ecosystem health status and fishery stocks based on comparison of ecological indexes among regions
Ocean circulation
Studies of ocean circulation influence on dispersion, retention and productivity of biota in the Gulf of California
Meteorology and oceanography explaining climatic changes
Meteorological and oceanographical studies driven to understand climatic change at distinct time and space scales
Modelling
Mathematical models to explain climatic change to any biota complexity among different ecosystems
Why the workshop?
This web workshop intent to gather students, scientists, and experts interested to integrate information to evaluate which is the current ecosystem health status of the Gulf of California and investigate resilience under likely prolonged climatic anomalies
Rationale of the web workshop: Satellite mean Sea Surface Temperature show a positive anomaly (A,C) and a prolonged Sea Surface Chlorophyll-a concentration comparing 2014–2020 against 2000–2013 (B,D). The main question of the web workshop is which is the ecosystem response to such climatic changes in the Gulf of California?
During the end of the workshop (Nov 20, 2020, 10-12 h) we will have a Discussion section analyzing the main conclusions of the web workshop with emphasis on the organization of present and future research work efforts to understand the current ecosystem status of the Gulf of California.
Additionally, we will to discuss and organize a publication of the results obtained during the web workshop as independent review or original research articles to be submitted as special issue in Marine Ecology Progress Series, or Progress in Oceanography; or alternatively as different chapters of a Springer Nature book with the name of the web Workshop. This decision well be taken with the consensus of most of the participants interested to submit a manuscript. Guess Editor Dr. Jaime Gómez- Gutiérrez (open for more volunteer guess editors).

ABSTRACT. Dosidicus gigas (jumbo or Humboldt squid) is an ecologically relevant predator in the Gulf of California, Mexico, where it supports an economically valuable fishery. The commercial jumbo squid fishery in the Gulf declined steeply after an El Niño event in 2009–2010, and subsequent landings have remained at historically low levels in the relevant squid fishing centers (Guaymas, Sonora, and Santa Rosalı́a, Baja California Sur). We examined wind speed and chlorophyll-a concentrations on the jumbo squid fishing grounds as factors that would be expected to be relevant to this prolonged period of low landings. Analysis from local weather stations, remote sensing, and fishery data showed that low jumbo squid landings from 2010 to 2015 occurred during a period of abnormally weak winter/spring winds and extremely low chlorophyll-a concentrations off the East Guaymas Basin. Results indicate that the squid fishing are in the Guaymas region has been chronically impoverished during this period, and that this area may no longer be a productive habitat for jumbo squid. In response to this decreased productivity, size-at-maturity of jumbo squid showed a drastic decrease over the same period. Results are compared with the effect of El Niño 1997–1998 on the jumbo squid fishery and size-at-maturity of this species in the Gulf of California. The key difference
