An evaluation on the proximity of satellite- and model-based datasets of temperature and chlorophyll-a in coastal areas of İskenderun Bay

Abstract

This study investigates the monitoring of sea surface temperature (SST) and chlorophyll-a (Chl-a) levels in Iskenderun Bay using satellite and modeling data and evaluates the possible use of these datasets for monitoring marine ecosystems. Datasets derived from MODIS-Aqua satellite imagery and modeling data obtained from the Copernicus MyOcean and in-situ measurements were used in the study. According to the analysis on paried data sets of the distribution of SST and chl-a, sattelite and model datasets showed statistically significant correlations with in-situ measurements for SST. However, only satellite dataset showed significant correlations for chl-a. Evaluations on uncertainty of the data sets revealed that the satellite dataset had a narrower range and less outlier distribution for SST. For chlorophyll-a, both datasets had wide uncertainty ranges and required further improvement. This study highlights the potential of satellite and model datasets for monitoring SST and chl-a variations in Iskenderun Bay.

Öz

Bu çalışma, İskenderun Körfezi'nde yüzey suyu sıcaklığı (SST) ve klorofil-a (Chl-a) düzeylerinin uydu ve modelleme verileriyle izlenmesini ve bu veri setlerinin deniz ekosistemlerinin izlenmesinde kullanılabilirliğini araştırmaktadır. Araştırmada yerinde ölçüm veri seti, MODIS-Aqua uydu görüntülerinden elde edilen veri seti ve Copernicus MyOcean veri setinden alınan modelleme verileri kullanılmıştır. Körfezdeki SST ve chl-a dağılımı için eşleştirilmiş veri setleri üzerine yapılan analizlerin sonuçlarına göre, SST için uydu ve model veri setlerinin, klorofil-a için ise uydu veri setinin ölçüm verileri ile istatistiksel olarak anlamlı korelasyona sahip olduğunu belirlenmiştir. Veri setlerinin belirsizliği üzerine yapılan değerlendirmeler, SST için uydu veri setinin daha dar bir yayılıma ve daha az aykırı değer dağılımına sahip olduğunu ortaya koymuştur. Klorofil-a için her iki veri setinin de yüksek belirsizlik aralıklarına sahip olduğu ve daha fazla geliştirmeye ihtiyaç duyduğu görülmüştür. Bu çalışma, İskenderun Körfezi'nde SST ve chl-a değişkenlerinin izlenmesi için uydu ve model veri setlerinin kullanılabilirliğini göstermektedir.
