“…Emery and Neev (1960) and Stanley (1989) report heavy mineral assemblages that point to a Nile source of sand for Israeli beaches. These observations are consistent with models of sediment transport northward by longshore currents from Sinai to the northern coast of Israel, as outlined by Goldsmith and Golik (1980) and Zviely et al (2007). Although the carbonate fraction of Israeli aeolianites is believed to be derived from local bioclastic sources, longshore transport of Nile Delta sand eastward along the Mediterranean has long been used to explain the origin of the non-carbonate fraction of aeolianite dune sands (Emery and Neev, 1960;Yaalon, 1967;Horowitz, 1979;Frechen et al, 2001).…”

"Origin of the Sinai-Negev erg, Egypt and Israel: mineralogical and geochemical evidence for the importance of the Nile and sea level history" (2013 Overall, the mineralogical data suggest that the dunes are derived dominantly from the Nile Delta, with Sinai wadi sands being a minor contributor. Geochemical data that proxy for both the light mineral fraction (SiO 2 /10eAl 2 O 3 þ Na 2 O þ K 2 OeCaO) and heavy mineral fraction (Fe 2 O 3 eMgOeTiO 2 ) also indicate a dominant Nile Delta source for the dunes. Thus, we report here the first empirical evidence that the SinaieNegev dunes are derived dominantly from the Nile Delta. Linkage of the SinaieNegev erg to the Nile Delta as a source is consistent with the distribution of OSL ages of Negev dunes in recent studies. Stratigraphic studies show that during the Last Glacial period, when dune incursions in the SinaieNegev erg began, what is now the Nile Delta area was characterized by a broad, sandy, minimally vegetated plain, with seasonally dry anastomosing channels. Such conditions were ideal for providing a ready source of sand for aeolian transport under what were probably much stronger glacial-age winds.With the post-glacial rise in sea level, the Nile River began to aggrade. Post-glacial sedimentation has been dominated by fine-grained silts and clays. Thus, sea level, along with favorable climatic conditions, emerges as a major influence on the timing of dune activity in the SinaieNegev erg, through its control on the supply of sand from the Nile Delta. The mineralogy of the SinaieNegev dunes is also consistent with a proposed hypothesis that these sediments are an important source of loess in Israel.Published by Elsevier Ltd.

“…Hamad et al's analysis indicates that there is a direct link between water flowing from the Aegean Sea, where M. leidyi has occurred since 1990, to the Levant. Alternatively, because the swarms of M. leidyi were observed mainly in the southern half of Israel, between Ashkelon and Netanya and considering that the predominant current in this region is along shore from south to north (Rosentraub & Brenner, 2007;Zviely et al, 2007), it is possible that M. leidyi was released in ballast water from ships traveling toward the southern Israeli port of Ashdod or to Egypt.…”

Blooms of the invasive ctenophore, Mnemiopsis leidyi, span the Mediterranean Sea in 2009

Blooms of the invasive ctenophore, Mnemiopsis leidyi, occurred in 2009 along the Mediterranean Sea coasts of Spain and Israel. This voracious zooplanktivore spread throughout the Black Sea basin after its introduction in the early 1980s, throughout northern European coastal waters, and now occurs throughout the Mediterranean Sea. M. leidyi occurred throughout the summer along the entire Catalan Spanish and Israeli coasts in 2009. Those locations had high temperatures (18-26°C) and salinities (37-38) during the blooms. The patterns of abundance of large jellyfish along the Catalan coast were unusual in 2009, with low numbers during July, August, and September when ctenophores were abundant. Small populations of those potential predators and food competitors of M. leidyi could have contributed to the ctenophore bloom. The identity of the ctenophores from Spain and Israel was confirmed as M. leidyi by molecular analysis based on DNA sequencing of the nuclear internal transcribed spacer (ITS) regions. This is the first molecular confirmation of M. leidyi in the Mediterranean Sea. Most ctenophores had an ITS genotype previously found in M. leidyi from other invaded regions (the Black, Azov, and Mediterranean seas), as well as native regions in the United States, suggesting common ancestry. Based on the circulation patterns of Mediterranean surface waters and shipping activities, we conclude that the spread of M. leidyi in the Mediterranean probably resulted from re-introductions by ballast water transport and subsequent distribution by currents. We also conclude that the near-simultaneous blooms in opposite ends of both the Mediterranean basins indicate that M. leidyi is resident around the Mediterranean. We discuss environmental conditions, food, and predators of M. leidyi in both regions that would influence the future effects of this voracious consumer on the pelagic food web of the Mediterranean Sea.

“…Where, the lateral variation from laminated sandstones (lithofacies 1) to massive sandstone (lithofacies 4); and high percentage of calcium carbonate in this lithofacies indicate to increase in the concentration of the sediments and rapid deposition. That sediments originate from the Nile delta (Horiwitz, 1979), and have been spread along the Sinai and Palestine coasts by longshore currents (Goldsmith & Golik, 1980;Coleman et al, 1981;Inman & Jenkins, 1984;Rohrlich & Goldsmith, 1984;Carmel et al, 1985;Stanley, 1989;Frihy et al, 1991;Frihy & Lotfy, 1997;Zviely et al, 2007;Zaineldeen, 2010) …”

The coastal plain of Gaza Strip is composed of an alternated kurkar and hamra deposits of Pleistocene to Holocene age. The hamra deposits consists of reddish brown sandy loam soils. The kurkar is mainly made of calcareous sandstones of marine and continental origin. Five marine lithofacies were identified along the coastal ridge within Gaza Strip which extends up to the current coastline of the Mediterranean Sea. These lithofacies are: (1) laminated medium-to very coarse-grained sandstones; (2) medium-to very coarse-grained cross-bedded sandstones; (3) graded coarse-grained sandstones; (4) massive coarse-grained sandstones; (5) bioclastic sandstones (calcarenite). The marine lithofacies identified in the study area belong to one of the two sedimentation zones: (1) the upper shoreface, represented by biogenic activities and marine fauna contents in sandy cross-stratification, and (2) the upper and lower foreshore, characterized by laminated with low-angle cross-stratification and channel deposits with low contents of marine fauna.
