We present a geostatistical analysis of oil spills using three databases for the Mediterranean Sea: REMPEC (1977-2000) with 385 spills (17/year), ITOPF (1970-2018) with 167 spills (3.5/year) and EMSA (2015-2017) with 2066 detections (688/year). It was found that 88% of spills reported by REMPEC occurred near coastline areas, while 65% of the spills detected by EMSA occurred within a range of 22-100 km from the coastline. At the Exclusive Economic Zone (EEZ) level, EMSA oil spills densities were positively correlated with shipping and port activity. We conclude that there is a need to develop an open-access database of oil spills that will be based on both reports and remote sensing acquisition methods. Such a database will facilitate more efficient enforcement of international conventions in offshore areas and will increase the likelihood of effective response.

Such information is necessary for managers and analysts to make strategic decisions and monitor the maritime industry in achieving management goals. In this study, we used monthly night light (NTL) images of the Suomi National Polar-Orbiting Partnership (Suomi NPP) Visible Infrared Imaging Radiometer Suite (VIIRS) Day/Night Band, between 2012 and 2020, to study the night lights emitted by ships in ports’ anchorage areas, as an indicator for shipping activity in anchorage areas and ports. Using a dataset covering 601 anchorage areas from 97 countries, we found a strong correspondence between NTL data and shipping metrics at the country level (n = 97), such as container port throughput (Rs = 0.84, p < 0.01) and maximum cargo carried by ships (Rs = 0.66, p < 0.01), as well as a strong correlation between the nu...

Be it the infamous plague (1347–1352), cholera (1817), yellow fever (1845–1846), typhus (1892), tuberculosis or influenza (1918), they all have spread through ships moving on the oceans. Unlike the earlier episodes, the recent pandemic,1 COVID-19, has not spread through ships. However, there have been some incidents wherein ships were quarantined or disallowed entry to ports due to COVID-19 cases onboard. As the number of affected nations increased, international borders were closed and lockdowns enforced to prevent a spread that brought businesses to a grinding halt. This notwithstanding, lockdowns provided a unique window of opportunity to scientists and environmentalist alike to study the environmental changes using automated monitoring techniques such as information technology and remote sensing technology. Of these, only a few of studies have focused on the environmental changes in the maritime domain. It is with this understanding that the paper aims to discuss the maritime domains impacted by COVID-19 (GHG and oil pollution, marine litter, fisheries, marine tourism, underwater noise and waste water discharge) to highlight the lessons to learn from the public-health-emergency, COVID-19, to address climate change, a public-health-emergency-in-waiting.

Within the last two decades, maritime domain has experienced a constant process of geopolitical and environmental change. The global growth of the population and rising living standards are continually increasing pressure on the marine environment, forcing it to generate resources and facilitating the transition from terrestrial resources to the search for new ones in the sea. As of today, maritime domains provide the main infrastructure and commercial connection to the rest of the world. Marine areas are also considered to be future land reserves for additional infrastructure construction and urban development. Additionally, the sea area is also a "blue lung," providing wide-open seascapes for recreation and entertainment. In this paper, we present a conceptual model “A Model for an Israeli Academic Marine Monitoring System” of the regional monitoring system of the sea territories based on modern methods of remote sensing and data processing.

The high correspondence levels of the VIIRS NTL data with various shipping indicators show the potential of using NTL data to analyze the spatio-temporal dynamic changes of the shipping activity in anchorage areas, providing convenient open access and a normalized assessment method for shipping industry parameters that are often lacking.

בעקבות שבע שנים של בצורת קשה (בין השנים 2000-2006), נצפתה תופעה של התייבשות יערות, הנמצאת במגמת עלייה. בדרום הארץ נמצאים אזורי יער גדולים תחת סכנה התייבשות. תהליך ההתייבשות יכול להיגרם כתוצאה מסיבות שונות. בין אלו ניתן למנות: שנות בצורת, עקה זמנית של יובש קיצוני, עלייה במשרעת הטמפרטורות, ירידה חדה בפוטנציאל המים באזור בית השורשים של העצים, מזיקים, מחלות, זיהום אוויר ושילוב של כמה מגורמים אלו גם יחד. את הגורמים להתייבשות אפשר גם לסווג לפי מידת השפעתם על עוצמת התהליך. ניתן לחלק גורמים אלה לשתי קבוצות: גורמים דינאמיים המשתנים בזמן ובמרחב וגורמים קבועים בזמן ובמרחב. כדוגמא לקבוצה הראשונה ניתן לציין את: כמות המשקעים, חדירות הקרקע, טמפרטורת הסביבה. בקבוצה השנייה ניתן לציין את: סוג הקרקע, המפנה, עומד היער והשיפוע.
תרומה עקיפה מהמחקר המוצע הינה בעצם סיווג עצים יבשים ובריאים ביער יתיר. זאת, על-ידי מציאת "פוליגונים של עצים מיובשים" בצורה אוטומטית. ניתוח תוצאות הרגרסיות איפשר להגדיר את עוצמת השפעתם של פרמטרים מרחביים שונים על תהליך ההתייבשות. על בסיס ניתוחים גיאו-סטטיסטיים שנערכו, נקבע לבסוף כי במודל החיזוי תיבדק השפעתם של: גובה, שנת הנטיעה, אנרגיה סולרית ושיפוע. המודל שנבנה נבחן במספר דרכים ונמצא אמין מאוד. מודל זה יוכל גם לעזור בהגדרת הפרמטרים המשפיעים ביותר ובלימוד האינטראקציה ביניהם על תהליך ההתייבשות ביער. בנוסף, בעזרת המודל המוצע ניתן יהיה לתכנן את מיקום הנטיעות הבאות על פני המרחב של יער יתיר.

Humans depend on oceans and seas' marine ecosystems for important and valuable goods and services... more Humans depend on oceans and seas' marine ecosystems for important and valuable goods and services, but human use has also altered the marine environment through direct and indirect means. Land-based and ocean-based human activities vary in their intensity of impact on the marine environmental conditions and their spatial distribution across the scape. Since opening the Suez Canal, the spatial distribution of such a human-made environmental change needs to be understood and quantified to be able to evaluate tradeoffs between the canal and the protection of the Mediterranean marine ecosystem. Such temporal and spatial evaluation will help to improve and rationalize the spatial management of the Mediterranean Sea of human activities. Evaluation of the ecological impact of the Suez Canal on the Mediterranean Sea requires a method for translating the impact into marine impacts and spatial data of the activities.
