“…There is the synchronization of internal and external rhythms ensuring the equilibrium between organisms and the environment [4,5]. Such interactions include circadian rhythms that modify the resistance and sensitivity of biosystems to harmful factors depending on light conditions [1,7,8]. Congenital circadian (daily, diurnal) rhythms are endogenous but synchronize with external factors and may be destroyed over time if external environmental conditions change [40,41].…”

Earlier, we showed that the registration of the behavioral responses of autochthonous mesozooplankton communities in situ is a more dynamic methodological approach in the biological assessment of the environmental well-being of aquatic ecosystems, as well as an alternative method to generally accepted tests on mortality and immobilization. The change in behavioral responses, including phototropic responses, may occur at lower concentrations of pollutants, leading to the inhibition of the risk-avoidance response of predatory fish attack and, ultimately, to the change in zooplankton abundance and biodiversity. The biological significance of such changes is quite high since zooplankters form the basis of food chains. This work studies the possibility of biomonitoring the quality of fresh water in Lake Baikal according to the state of the autochthonous mesozooplankton community in summer and winter using a digital holographic camera developed and tested by us in laboratory conditions. This method makes it possible to determine the concentration of plankters in the controlled volume of the DHC and perform photostimulation with different levels of illuminance. The depth profilometry of the phototropic response was compared with the profilometry of plankton concentration, intraspecific diversity of crustaceans according to the Pielou index, and the results of catching using the Juday net in the natural environment of the lake and during the modeling of the anthropogenic impact (introduction of table salt solution into the local area close to the registration probe). The circadian rhythm parameters were determined by the spectral analysis of the long-term registration of the phototropic response dynamics. It was noted that the inhibition of the phototropic response was the most adequate marker of the exogenous impact and the appearance of an alternating factor among the studied indicators of the state of the plankton community, namely, intraspecific diversity, synchronism of circadian rhythms, and response to paired photostimulation. The revealed patterns of behavioral responses of autochthonous zooplankton in natural and artificially modified conditions will allow for the implementation of long-term continuous control over the environmental well-being of water areas, including the collection ponds of treatment facilities, cooling ponds of nuclear power plants, and other water areas in contact with potentially hazardous facilities. The comparison of the identified patterns with the behavioral responses of euryhaline mesozooplankton will expand this method to assess the well-being of salt-water and marine reservoirs under the anthropogenic impact and will make it possible to create a continuous monitoring system.

“…The CCV Holographic Image Processing Pipeline (Fig. 2, herein referred to as the CCV Pipeline 5 ), developed by our group, is an unsupervised analysis package relevant to point‐source holographic microscopes that automates the process of determining the optimal focal depths of particles from the 4‐Deep Octopus software for high‐throughput hologram analysis (Walcutt et al 2019). First, the CCV Pipeline saves slices of the hologram (i.e., focal planes) from Octopus in user‐specified μ m increments across the 22 mm path between the point source and the camera.…”

Holographic microscopy has emerged as a tool for in situ imaging of microscopic organisms and other particles in the marine environment: appealing because of the relatively larger sampling volume and simpler optical configuration compared to other imaging systems. However, its quantitative capabilities have so far remained uncertain, in part because hologram reconstruction and image recognition have required manual operation. Here, we assess the quantitative skill of our automated hologram processing pipeline (CCV Pipeline), to evaluate the size and concentration measurements of environmental and cultured assemblages of marine plankton particles, and microspheres. Over 1 million particles, ranging from 10 to 200 μm in equivalent spherical diameter, imaged by the 4‐Deep HoloSea digital inline holographic microscope (DIHM) are analyzed. These measurements were collected in parallel with a FlowCam (FC), Imaging FlowCytobot (IFCB), and manual microscope identification. Once corrections for particle location and nonuniform illumination were developed and applied, the DIHM showed an underestimate in ESD of about 3% to 10%, but successfully reproduced the size spectral slope from environmental samples, and the size distribution of cultures (Dunaliella tertiolecta, Heterosigma akashiwo, and Prorocentrum micans) and microspheres. DIHM concentrations (order 1 to 1000 particles ml−1) showed a linear agreement (r2 = 0.73) with the other instruments, but individual comparisons at times had large uncertainty. Overall, we found the DIHM and the CCV Pipeline required extensive manual correction, but once corrected, provided concentration and size estimates comparable to the other imaging systems assessed in this study. Holographic cameras are mechanically simple, autonomous, can operate at very high pressures, and provide a larger sampling volume than comparable lens‐based tools. Thus, we anticipate that these characterization efforts will be rewarded with novel discovery in new oceanic environments.

“…Penerapan film empat dimensi (4D) di oseanarium memungkinkan pengunjung untuk merasakan sensasi fisik yang menyertai tontonan visual yang mereka saksikan. Ini menciptakan pengalaman yang lebih imersif, seolah-olah pengunjung benar-benar berada di dalam habitat laut yang ditampilkan (Walcutt et al, 2019). Misalnya, saat menonton film tentang kehidupan di terumbu karang, kursi yang bergerak dan efek-efek seperti semprotan air atau angin dapat meningkatkan pengalaman visual tersebut.…”

Oseanarium merupakan destinasi wisata populer di Indonesia. Artikel ini membahas transformasi digital dalam merancang oseanarium terkini. Metode penelitian melibatkan survei dan observasi ke 2 lokasi oseanarium utama di Jakarta, satu oseanarium di Singapura dan satu lagi di siam paragon Bangkok, guna mendapatkan gambaran tentang operasional, dan implementasi teknologi digital. Selain itu, penelitian ini juga mengintegrasikan pengalaman penulis sebagai desainer publik Akuarium dan selama 20 tahun sebagai pengelola di salah satu publik akuarium di kawasan Jakarta. Strategi saat ini harus menggunakan teknologi IoT untuk sistem manajemen energi pintar dan pemantauan lingkungan akuatik. Temuan ini menunjukkan bahwa penggunaan teknologi interaktif di banyak lokasi dapat memberikan pengalaman edukasi yang menarik dan tak terlupakan bagi para pengunjung. Salah satu teknologi yang menarik dan disukai bagi pengunjung adalah penggunaan teknologi hologram, pengunjung dapat merasakan sensasi berada di dalam laut dan berinteraksi dengan hewan-hewan laut dalam lingkungan virtual yang realistis. Hal ini meningkatkan pemahaman mereka tentang kehidupan akuatik dan nilai melindungi lingkungan laut. Transformasi digital ini tidak hanya meningkatkan efisiensi operasional oseanarium, tetapi juga memperkaya pengalaman pengunjung melalui penerapan teknologi interaktif. Dengan mengimplementasikan rencana ini, diharapkan oseanarium di Indonesia akan memperluas dan menghasilkan manfaat bagi kelestarian ekosistem laut, meningkatkan pengetahuan masyarakat tentang biologi biota laut, dan memberikan pengalaman berkualitas tinggi bagi pengunjung.
