According to the public relations office of Persian Gulf and Oman Sea Ecology Research Institute-Bandar Abbas, the first naval patrol was carried out in 9 stations to conduct sampling operations for the project of studying the bloom of microalgae in Persian Gulf and Oman Sea (Hormozgan province) using satellite images simultaneously with satellite observation of Hormoz-Qeshm waters. In this study, water sampling was performed to identify microalgae (phytoplankton), measuring chlorophyll a and nutrients. Some physicochemical factors such as salinity, oxygen, temperature and pH were performed using a portable multi-parameter device. In Persian Gulf and Oman Sea, as in many aquatic ecosystems, microalgae often thrive pursuant to water discoloration with little or no damage to aquatic life. However, sometimes the destructive effects of this phenomenon have been recorded, including the death of fish, sea and coastal birds, marine mammals and aquatic invertebrates, and other aquatic animals. In addition to endangering aquatic lives, this causes problems for people living on the coast. So the need for continuous monitoring of coastal waters in order to identify blooms and sometimes "harmful" algae blooms is essential. Water sampling often involves the identification of microalgae (phytoplankton), chlorophyll a. Satellite imagery, also provides regular coverage of vast areas with spatial and temporal resolution. Due to the spectral properties of photosynthetic pigments at the water surface and the possibility of identifying them with satellite images, the algal bloom can be monitored by processing these images along with environmental information. In this research, sampling stations in the waters of Hormozgan province have been determined and samples will be collected on a monthly basis. In addition, it is anticipated that if reports of a blooming event are received, sampling will be performed within that time frame and satellite imagery will be extracted at the same time. The four areas under study will include: the waters around Hormoz-Qeshm, Bandar Abbas, the coastline of Bandar Abbas and Bandar Lengeh. The specific day and time of satellite transit and observation announced by the space organization is the basis of the time of field operations which in this case it will be possible to match field and satellite data.
