 ==== 1.3 Product ====
-The idea of this project is to create a marine habitat for underwater enviroments, in order to promote the live of the diferent species that habit the the seabed of the coastal plate. Since this is the environment of many endangered species and its a global problem, our goal is to improve this situation while monitoring the characteristics that may affect this danger that threat the sea life.
-For this project, we have thought of an structure made to sit in the sea floor, with the purpose of being colonized by many aquatic species to use it as a shelter where to follow their natural way of living. This intends to recreate a natural environment, and ir order to get that we need to review the most suitable material, as well as the best designs for the viability of the project.
+==== 1.3 Product ====
-To fulfill the task of monitoring the conditions, we have to research about the sensors that can take that job properly, and an organizational model that allow as to get information we need, without disturbing the environment and complying with all regulations.
+MARIS HABITATS is a modular reef infrastructure and environmental monitoring system designed for underwater environments. The product combines physical reef blocks with a removable smart sensor box, allowing it to provide both structural support and long-term environmental data.
-Finally, our final target it is to create social awareness, the amount of trouble is going under the sea it is a big problem, and most of the people doesn't even know about it. With all the information we can recolect, the best chance is not only with the science or research, it is to concern people about the biggest resource on earth, the sea.
+The reef blocks are designed to be placed on the seabed and to create surfaces, cavities, and sheltered spaces that may support habitat formation over time. Instead of claiming immediate biological recovery, the product focuses on providing a physical structure that can be used in marine restoration, research, or environmental monitoring projects.
+The smart sensor box collects environmental data from selected locations around the reef structure. This data can help users understand local site conditions and observe how the reef and surrounding marine environment change over time. The monitoring system is designed to operate with low power consumption and store data locally, reducing the need for continuous communication infrastructure.
+The final product is intended for organizations such as public institutions, coastal municipalities, research groups, environmental NGOs, port authorities, aquaculture operators, and marine infrastructure companies. These customers may use MARIS HABITATS as part of restoration projects, long-term monitoring programmes, sustainability reporting, or environmental decision-making.
 ==== 1.4 Problem ====
-The basis for develop this idea starts on a global view of a huge environmental problem, the sea is dying. The causes of this problem are multiple; the global warming is raising not only the level of the oceans but the temperature of them. This is alterating the conditions of most of the underwater eco-systems, and this evolves in multiple species having to migrate from their original enviroments to new ones.

-Another big problem is the massive fishing made by human hands. All around the wolrd, fishing is a daily practice, and even it is strongly regulated by governments and various institutions, it has affected the natural cycle of the sea-life. Now it has become a huge problem, since a lot of fish species are being depleted and others are being affected by the food chain, every creature in the sea is in danger.

-The third big issue going on, concerns the levels of oxygen in the sea. With most of the fauna being altered, the flora is also damaged, the Great Barrier Reef and other coral reefs responsible of producing between 60 % and 80 % of the oxygen we breath, are rapidly dying, already more than 50 % of it has died in the last decades, so a global problem is incoming, and it is our job to do the possible to solve it.

 ==== 1.5 Objectives ====
-This project focuses on developing a sustainable and technically feasible solution to remediate the loss of seafloor habitats. Our goal is to counteract current environmental decline by providing artificial structures that serve as refugia for marine life, thereby enhancing biodiversity and population recovery.
-More specifically, the objectives are:
+This project focuses on developing a sustainable and technically feasible concept for a modular artificial reef system with environmental monitoring functions. The main goal is not to prove immediate biological recovery, but to design a reef structure and a basic sensing system that can support future marine restoration and monitoring projects.
-  - Create an appropiate structure for life to happen.
-  - Ensure the sustainability without life disturbance.
-  - Recolect information from this habitats to improve them.
-  - Create social awareness about the situation and the urge for a solution.
+The first objective is to design a modular reef structure that can be adapted to different sites and project sizes. The structure should be made of repeatable blocks that can be combined in several ways. These blocks should provide surfaces, cavities, and sheltered spaces that may support habitat formation over time.
+Another important objective is to select materials that are suitable for marine conditions. For the final design, durable and environmentally compatible materials, such as basalt fiber-reinforced concrete, are considered because they can improve resistance to seawater conditions and reduce long-term environmental risks [(FIORE2015)], [(QU2021)].
+The project also aims to include a removable monitoring unit. Instead of placing electronics permanently inside the reef structure, the system should use a smart sensor box that can be separated from the main habitat. This makes it easier to check, repair, or replace electronic components without removing the whole reef from the seabed.
+A further objective is to collect useful environmental data. In the final system, the intended parameters include temperature, pressure or depth, pH, and conductivity. This data can help users understand the conditions around the installation site and observe how the surrounding marine environment changes over time.
+For the prototype, the objective is more limited. The prototype is intended to validate the basic sensing and data logging concept under controlled conditions. Due to budget and component availability, it uses a simplified sensor set, including temperature, pressure, and TDS. The pH and conductivity sensors are reserved for the final product.
+Finally, the project aims to reduce unnecessary disturbance to the marine environment. The removable sensor box allows maintenance, battery replacement, and data collection to be carried out without disturbing the main reef structure. This also reduces the risk of leaving failed electronic components underwater.

 ==== 1.6 Requirements ====
+This section defines the main requirements of the MARIS HABITATS system. The requirements are divided into functional and non-functional categories. Functional requirements describe what the system should do, while non-functional requirements define the conditions needed for safe and reliable operation in a marine environment.
+Because the project separates the final product from the prototype, the requirements are also considered at two levels. The final product is intended for long-term marine deployment, while the prototype is designed to validate the basic sensing and data logging concept under controlled conditions.
 === 1.6.1 Functional Requirements ===
-The system must collect and transmit real-time environmental data (e.g., water temperature, pH levels, turbidity) using sensors at pre-defined intervals.
+The final system must collect environmental data at predefined time intervals. The intended final measurement parameters include water temperature, pressure/depth, pH, and conductivity.
-A reliable wireless communication protocol must be established to send data to a cloud-based dashboard for real-time analysis.
+The prototype uses a simplified sensor set due to budget and component availability. For prototype testing, the measured parameters include temperature, pressure, and Total Dissolved Solids (TDS). The pH and conductivity sensors are reserved for the final product.
-The solution must incorporate energy-harvesting mechanisms (such as solar or wave energy) and utilize Deep Sleep modes to ensure continuous operation without external power.
+The collected data must be stored locally using a data storage unit such as a Secure Digital (SD) card. This allows long-term operation without relying on external communication infrastructure or real-time underwater data transmission.
-The structure must provide complex cavities and textured surfaces, specifically designed to encourage the settlement of local marine species [[#ref39|[39]]].
+Energy consumption must be minimized to extend the operational lifetime of the monitoring system. This is achieved through low-power operation, where the system remains active only during short measurement cycles.
+The system must perform measurements periodically, typically once per hour. During each cycle, the system remains active only for the time required to stabilize sensor readings and store the data.
+The smart sensor box must be removable so that battery replacement, sensor inspection, maintenance, and data retrieval can be carried out without removing the whole reef structure from the seabed.
+The physical reef structure must include cavities, textured surfaces, and sheltered spaces that may support the attachment and growth of marine organisms over time [(Graham2013)].
 === 1.6.2 Non-Functional Requirements ===
-To avoid failures observed in projects such as Osborne Reef, the structure must be composed of pH-neutral, non-toxic, and eco-friendly materials that do not release harmful substances into the marine environment [(OsborneReef2024)] [(Artificial reef preparation)].
+In addition to functional capabilities, the system must satisfy several non-functional requirements to ensure safe and reliable operation in marine environments. Since the structure is deployed underwater and interacts directly with marine ecosystems, material selection, structural stability, waterproofing, and maintenance access are critical.
+To avoid environmental risks, the structure must be made from durable, non-toxic, and environmentally compatible materials that do not release harmful substances into the marine environment. Poorly selected artificial reef materials can create long-term environmental problems, as shown by previous failed reef projects such as Osborne Reef [(OsborneReef2024)].
+For the final product, basalt fiber-reinforced concrete is considered as the main structural material because basalt fibers are known for corrosion resistance and chemical stability in marine environments [(FIORE2015)].
+The structure must be designed to remain stable under expected currents and wave conditions without displacement. Artificial reef guidelines emphasize that reef materials should be stable and remain at the intended deployment site [(NOAA2007)].
-The habitat must be designed to withstand high currents and storm surges without displacement or structural failure.
+All electronic components, including sensors, batteries, and storage units, must be enclosed in a waterproof housing with at least IP68 protection to prevent water ingress and support underwater operation [(IP68)].
-All electronic components, including sensors and batteries, must be enclosed in IP68-rated waterproof housing to resist saltwater corrosion [[#ref23|[23]]].
+The monitoring unit must be designed to reduce the risk of leakage, corrosion, and internal moisture. Moisture-absorbing materials may be used inside the enclosure to help control condensation.
-The design should allow for modular expansion and easy access for sensor or battery replacement if necessary.
+The design must allow access for maintenance, battery replacement, and data retrieval. This is especially important because the system stores data locally and requires scheduled retrieval.
+The prototype does not need to meet the same marine-grade requirements as the final product. It is intended for controlled testing and should be clearly presented as a simplified validation model rather than a final deployable system.
