“…Due to such importance, and thanks to the current and rising measurement abilities, those two properties are among the most monitored and used data, which makes them an attractive alternative for emulation of an actual, mostly conservative, solute transport. Several studies used salinity [33,35,36,38,39] or temperature [33,69,70] as an indicator for other properties in rivers and estuaries. Hence, sea water dilution (supported by both salinity and temperature data) may be considered as an inverse process to river transport by freshwater discharge, as freshwater both dilutes the salinity and decreases the temperature.…”

There are multiple factors affecting the behavior of water properties in an estuary, including the hydraulic properties of rivers and corresponding receiving water bodies, along with the potential solutes brought by rivers. Although there are various numerical models and analytical approaches to solving particular or holistic problems in estuaries, measurements are inevitably required. In this study, we developed an innovative low-cost probe based on the Arduino platform as an alternative to more expensive measuring systems. Our device is designed to measure position, temperature, and electrical conductivity in multiple realizations, and it consists of a floating container equipped with the following components: an Arduino Mega development board, a power management module, an SD card logging module, a Bluetooth module, a temperature measuring module, a global positioning satellite (GPS) position module, and a newly developed module for measuring electrical conductivity (EC). We emphasize that all used tools are open-source and greatly supported by the worldwide community. We tested our probe during a field campaign conducted at the estuary of River Jadro near Split (Croatia). Nine probes were released at the river mouth and their position, temperature, and EC were monitored and recorded during the experiment, which ended when the probes stopped, due to the river plume attenuation. The same experiment was repeated three times. All of the probes recorded consistent temperature data, while the EC data show more variable behavior, due to the higher sensitivity of the corresponding sensor. This was expected as a part of the natural process in the estuary. The measured data were additionally used to parameterize an analytical model for mean flow velocity and salinity as a proxy concentration. This showed a good match between the experimental results and the theoretical framework. This work, although focused on water surface applications in the near field zone of an estuary, should be considered as a promising step toward the development of innovative and affordable measurement devices.

“…In the productive basis of this system, zooplankton communities are the main intermediate components of the pelagic food web, transferring energy and phytoplankton matter to higher trophic levels (Oliveira et al, 2015;Cepeda et al, 2018). Secondary production measures can be used to characterize the functional role of zooplankton and evaluate the impacts on ecosystem processes and services (Araújo et al, 2017;Isinibilir;Dogan, 2019;Setubal et al, 2020).…”

The equatorial Atlantic is characterized by its high abundance of zooplankton. However, starting point studies concerning the species composition in the northern Brazilian continental shelf are still scarce. Species cataloging studies can help to know the diversity of this ecosystem and, consequently, develop conservation studies and strategies for natural resources management. Thus, this work aims to characterize the species composing the zooplanktonic communities present on the continental shelf of Maranhão. Ninety-six taxa distributed among the Radiolaria, Myozoa, Foraminifera, Cnidaria, Mollusca, Annelida, Arthropoda, Bryozoa, Chaetognatha, Echinodermata, Chordata, and other groups, were recorded. The composition of mesozooplankton showed a wide distribution, indicating that the species are finding the appropriate conditions for their development.

The dominant zooplankton of the La Mancha lagoon, Veracruz, Mexico, was analyzed with the objective of evaluating its seasonal and diel variability, as well as the influence of the main environmental variables on this variability. From May 2012 to April 2013, every month a 24-h cycle was completed, taking samples every 4 h, at the mouth of the lagoon. Simultaneously with zooplankton sampling, in situ environmental parameters such as temperature, dissolved oxygen, salinity, chlorophyll a and number of phytoplankton cells were recorded. We collected 54 taxa (mainly holoplankton) and 10 of them were considered dominant (total abundance > 0.5%). The zooplankton community was dominated mainly by two species of copepods (Acartia tonsa and Pseudodiaptomus pelagicus), as well as zoea larvae of brachyura (~85%). At seasonal level, the total abundance of zooplankton showed significant pulses throughout the year, one in February-March dominated by copepods and another in September-October, dominated by decapod larvae. On a diel scale, although total zooplankton abundance was significantly higher at night, only P. pelagicus, amphipods, megalopae, and other decapod larvae showed significant differences at this level. According to a Canonical Correspondence Analysis, the mouth stage (open/close), the number of cyanophytes and precipitation were the most important environmental factors in determining the abundance of the dominant zooplankton.
