Status index of optimal water variables for biodiversity conservation in the Lagoon of Sonso in Colombia

Abstract

In order to determine an index of the status of optimal water variables for biodiversity conservation in the Sonso Lagoon, the data obtained from 2004 to 2018 were used. To determine the index, a methodology based on a multivariate analysis of the physical-chemical water variables was used, as well as a correlation analysis for their delimitation. Subsequently, the definition of weights and the parameterization of the variables for the final construction of the index were made. As a result, it was found that the lagoon is in an adequate state with a value index of 0.65, with a highly vulnerable tendency to be in an acceptable state and go to a critical state, depending on the anthropic pressure it has. As a conclusion, it was obtained that variables such as dissolved oxygen, total phosphorus and electrical conductivity are determining factors in establishing the index.

Seawater salinity modelling based on electromagnetic wave characterization

“…Accurate propagation should be known for each specific environment to tackle mainly the various parameters such as path loss and fading which affect the coverage area and improve receiver sensitivity, respectively [4]. Each up to now the wireless model has its own applicability standards and limitations, including various antenna's specification [5], but up to the present, no study takes care of the gradient seawater salinity despite the area such as the Gulf region and others having a distinguished environment and stark salinity that has been variating from place to another inside the water [6], [7]. This phenomenon gives a crucial warning when considering the coastline link design to investigate the signal behavior well when bouncing from the salt seawater and diffusely reflected in many directions.…”
