“…The Gulf of Mexico Research Consortium (CIGoM) and other institutions in Mexico carried out a project to understand how the Gulf of Mexico is being exposed to oil exploitation [10,11]. Oil exploitation is one of the most polluting economic activities with critical importance but it carries risks; it can disrupt complex ecosystems and the environment of the region [12].…”

Submarine gliders are specialized systems used in applications such as environmental monitoring of marine fauna, in the oil industry, among others. The glider launch and capture is a costly process that requires substantial technological and human resources, so the orderly and error-free storage of data is of fundamental importance due to the subsequent analysis. The amount of information being obtained from the seabed is increasing, this leads to the need to develop robust and low-cost ad-hocsystems for this type of application. The challenge is the integration of the different software layers in the storage system because the monitored variables must be ordered according to different glider operations such as calibration data update and navigation. Additionally, to avoid data corruption in the memory chip, error control coding must be used. The goal of this paper is to present a novel design of different layers of software integrated into a datalogger: reception, error control, and storage logic for the different glider operations. The design of the datalogger is based on a NAND flash memory chip and an MSP430 microcontroller. To correct bit-flipping errors, a BCH code that corrects 4 errors for every 255 bits is implemented into the microcontroller. The design and evaluation are performed for different glider operations, and for different lengths and correction capabilities of the BCH module. A test to calculate the storage time has been carried out. This test shows that in the case of 256 bytes per sample, at 30 samples per minute, and 1 GB of storage capacity, it is possible to collect data from the glider sensors for 84 days. The results obtained show that our device is a useful option for storing underwater sensor data due to its real-time storage, power consumption, small size, easy integration, and its reliability, where the bit error rate BER is of 2.4 ×10−11.

“…This area is a key marine ecosystem in terms of connectivity within the GM and the Caribbean (Aguilar-Medrano and Vega-Cendejas 2019), with a great diversity of marine and coastal habitats such as sandy and macroalgae, seagrass beds, rocky, and reef systems (Contreras 1993;Rivera-Arriaga et al 2003;Felder and Camp 2009). It is recognized as an important center of marine and estuarine biodiversity of crustaceans (Rubio-Polania et al 2018) and fish (Palacios-Sánchez et al 2015;Robertson et al 2019), with the presence of endemic and cosmopolitan species (García-Ríos et al 2013) likewise, CB has been recognized with great benthic biodiversity susceptible to negative impacts, such as ocean acidification, fish trawls, hurricanes, storms, and marine traffic (Ocaña et al 2019).…”

Campeche Bank located in the Yucatan Peninsula, Mexico is characterized by particular oceanographic and physiographic conditions that promote great biodiversity, including abundant fishery resources. Systematic sampling through oceanographic campaigns (November 2015, April 2016), produced high-quality data to generate a trophic model balance using Ecopath software. The goal of this study is to know the baseline of the structure and functioning of this important marine area. The predator/prey matrix was drawn up from the stomach content analysis of 186 fish species integrated into 47 families. The schematic representation exemplifies a complex trophic interaction of 22 trophic groups, including 10 fish groups, 8 invertebrate, zooplankton, phytoplankton, benthic producers, and detritus. Production and consumption of biomass and ecotrophic efficiency values were calculated for each of the trophic groups. The Total System Throughput was of 319.514 t/km 2 /year. The Ascendency, system Overhead, and Development Capacity were of 476.4, 673.1, and 1150.0 flow bits, respectively. Campeche Bank is an oligotrophic system with an intermediate state of resilience to environmental variations, growth potential intermediate, and greatly influenced by loop and Caribbean currents. These properties together with indicators of overfishing in the system and pollution (hydrocarbons), highlight the requirement of controlling fishery pressures and monitor hydrocarbons industry in the area to maintain its function and biodiversity.
