Detection and Tracking of Mucilage Phenomenon in the Sea of Marmara by Remote Sensing Images
(Istanbul Univ Press, Istanbul Univ Rectorate, 2025) Kucuk, Sefa; Abaci, Bahri; Dede, Murat; Yuksel, Seniha Esen; Yilmaz, Mete
Marine mucilage is a collection of mucus-like organic matter released by marine microorganisms. Intense mucilage formation in the sea prevents fisheries, maritime, and tourism activities, reduces oxygen levels, and adversely affects biodiversity. The traditional method of detecting mucilage involves taking samples from the sea and analyzing them in a laboratory. However, detecting mucilage with these standard methods is laborious since it can spread over kilometers. On the other hand, several satellites in orbit regularly collect data from the Earth's surface, making it possible to monitor the presence of mucilage through satellite data analysis. Therefore, using both traditional and deep learning algorithms, we utilized PRISMA hyperspectral and Sentinel-2 multispectral data to detect mucilage in its early stages. Sentinel-2A has four 10m fine bands and six 20m coarse bands. To benefit from all bands of Sentinel 2A, the spectral bands must have the same spatial resolution. Although the Sentinel-2A does not have a panchromatic band, the spatial resolution of the 20m bands has been increased to 10m employing its four fine bands as a panchromatic band. We aim to identify or construct a suitable panchromatic band for coarse bands using seven of the existing pansharpening techniques to enhance the spatial resolution of 20m bands to 10m. After preprocessing, we comprehensively compare four different methods, namely Linear regression, Random forest, U-Net, and Vescovi index, on two datasets. On the multispectral dataset, we correctly detect 87.8% of the mucilage formations with the U-Net model and achieve the area under the curve (AUC) score of 0.977. However, the Random forest model has outperformed the other methods, identifying 89.8% of the mucilage formations on the hyperspectral dataset. Experimental results on satellite data with multiple resolutions, bands, different days, and times indicate that detecting mucilage from satellite data with high accuracy and without massive effort is possible.

The Nativity by Ahdaf Soueif: Egyptian Zar as Heterotopic Space
(Vernon Press, 2023) Circir, Ayse
Ayse Circir uses fiction to explore, in more depth, elements of religiosity from the experiences of women migrants in contemporary Britain. The last story in Aisha, "The Nativity", demonstrates a religious ceremony with scathing elegance. The story describes z (a) over bar, a female-only ritual, and at the centre of the depictions are biblical, Islamic, and mythological overtones and perennial contradictions. Aisha, a childless woman, also a graduate of English Literature, returns to her native land Egypt after spending some time in England. She visits the mosque of Sidi Abul Suoud, the Healer of Hearts, to break the knot and thus have a child. Her nurse Dada Zeina, a lower-class character, encourages and presses her to visit the saint to overcome her childlessness. Aisha attends za (a) over bar and presences, recites English Romantic poetry during zikr and dance, whispers verses from the Qur'an while thinking about sacrificing sheep for the saint and questions the suggestion of bribery. There are paradoxes in the story, cathedrals and mosques, Bacchanalia and Islamic recitations, the city of the living and the City of the Dead, jinni and human beings, withdrawal and rape, and life and death. Fittingly titled "The Nativity", the story looks at birth, death, and fertility and, as a Muslim woman, Aisha realises that she can neither set up a zar of her own, nor join the z (a) over bar of others. She is trapped in-between, just like the jinni who wants to own her but has to destroy her in doing so. In closer focus, the reader recognizes that the story is narrated by a jinni who obsessively follows Aisha, the narrative actually starts with a prologue. Although the ending is tragic, she draws attention to the fact that z (a) over bar is constructed as a liberating space. As lived religion, z (a) over bar has provided solidarity and support for women since colonial invasion and, by looking at religion from this perspective, Soueif shows that an activity that is described as irrational could be subject of literature. In this light, Dr. Circir's study argues that z (a) over bar in "The Nativity" is addressed not only as an answer to the patriarchal and hegemonic discourse of official Islam, but also as subject of English Literature. Fact and fiction in this chapter are interlinked. Although written in the past, "The Nativity" continues to bear relevance with today's British women. The debate continues on Muslim women wearing the veil. Conflict, in Syria has seen many leave their homes in search of safety. Yet how many feel a sense of belonging in their new countries? How many are viewed as a threat, or are othered? We can learn much from the pages of a book, be it fact or fiction.
