Trash Islands - the Ocean Garbage Patch

Trash Islands - the Ocean Garbage Patch As our global population expands, so does the amount of trash we produce, and a large portion of that trash then ends up in the worlds oceans. Due to oceanic currents, much of the trash is carried to areas where the currents meet. These collections of trash have recently been referred to as marine trash islands. The Great Pacific Garbage Patch The Great Pacific Garbage Patchsometimes called the Eastern Garbage Patchis an area with an intense concentration of marine trash located between Hawaii and California. The exact size of the patch is unknown, however, because it is constantly growing. The patch developed in this area because of the North Pacific Subtropical Gyre- one of many oceanic gyres caused by a convergence of ocean currents and wind. As the currents meet, the earth’s Coriolis Effect (the deflection of moving objects caused by the Earth’s rotation) causes the water to slowly rotate, creating a funnel for anything in the water. Because this is a subtropical gyre in the northern hemisphere it rotates clockwise. It’s also a high-pressure zone with hot equatorial air and comprises much of the area known as the horse latitudes. Due to the tendency of items to collect in oceanic gyres, the existence of a garbage patch was predicted in 1988 by the National Oceanic and Atmospheric Association (NOAA) after years of monitoring the amount of trash being dumped into the worlds oceans. The patch was not officially discovered until 1997, though, because of its remote location and harsh conditions for navigation. That year, Captain Charles Moore passed through the area after competing in a sailing race and discovered debris floating over the entire area he was crossing. Atlantic and Other Oceanic Trash Islands Though the Great Pacific Garbage Patch is the most widely publicized of the so-called trash islands, the Atlantic Ocean has one as well in the Sargasso Sea. The Sargasso Sea is located in the North Atlantic Ocean between 70 and 40 degrees west longitude and 25 and 35 degrees north latitude. It is bounded by the Gulf Stream, the North Atlantic Current, the Canary Current, and the North Atlantic Equatorial current. Like the currents carrying trash into the Great Pacific Garbage Patch, these four currents carry a portion of the worlds trash to the middle of the Sargasso Sea where it becomes trapped. In addition to the Great Pacific Garbage Patch and the Sargasso Sea, there are five other major tropical oceanic gyres in the worldall with conditions similar to those found in these first two. Components of Trash Islands After studying the trash found in the Great Pacific Garbage Patch, Moore learned that 90% of the trash found there was plastic. His research groupas well as NOAAhas studied the Sargasso Sea and other patches around the world and their studies in those locations have had the same findings. It is estimated that 80% of the plastic in the ocean comes from land sources while 20% comes from ships at sea. The plastics in the patches consist of items like water bottles, cups, bottle caps, plastic bags, and fish netting. It’s not just  large plastic items that make up the trash islands, however. In his studies, Moore found that the majority of the plastic in the worlds oceans is made up of billions of pounds of raw plastic pellets called nurdles. These pellets are a byproduct of plastics manufacturing. It is significant that most of the trash is plastic because it does not break down easilyespecially in water. When plastic is on land, it is more easily heated and breaks down faster. In the ocean, the plastic is cooled by the water and becomes coated with algae which shield it from sunlight. Because of these factors, the plastic in the world’s oceans will last well into the future. Garbage Islands Impacts on Wildlife The presence of the plastic in these patches is having a significant impact on wildlife in a number of ways. Whales, seabirds, and other animals can easily be snared in the nylon  nets and six-pack rings prevalent in the garbage patches. They are also in danger of choking on things like balloons, straws, and sandwich wrap. Additionally, fish, seabirds, jellyfish, and oceanic filter feeders easily mistake brightly colored plastic pellets for fish eggs and krill. Research has shown that over time, the plastic pellets can concentrate toxins which are passed on to sea animals when they eat them. This could poison them or cause genetic problems. Once the toxins are concentrated in the tissue of one animal, they can magnify across the food chain similar to the pesticide DDT. Finally, the floating trash can also aid in the spread of species to new habitats. Take, for instance, a type of barnacle. It can attach to a floating plastic bottle, grow, and move to an area where it is not naturally found. The arrival of the new barnacle could then possibly cause problems for the areas native species. The Future for the Trash Islands Research conducted by Moore, NOAA, and other agencies show that  trash islands are continuing to grow. Attempts have been made to clean them up but there is simply too much material over too large of an area to make any significant impact. Some of the best ways to aid in the cleanup of these islands are to suppress their growth by enacting stronger recycling and disposal policies, cleaning up the worlds beaches, and reducing the amount of trash going into the worlds oceans.

Pharaoh Amenhotep III and Queen Tiye

Pharaoh Amenhotep III and Queen Tiye Famed Egyptologist Zahi Hawass considers the Egyptian pharaoh Amenhotep III, one of the final rulers of the Eighteenth Dynasty, as the greatest monarch ever reign over the Two Lands. Dubbed the Magnificent, this fourteenth-century B.C. pharaoh brought in unprecedented amounts of gold to his kingdom, built tons of epic structures, including the famed Colossi of Memnon and lots of religious buildings, and depicted his wife, Queen Tiye, in an unprecedentedly egalitarian fashion. Lets dive into the revolutionary era of Amenhotep and Tiye. Amenhotep was born to Pharaoh Thutmose IV and his wife Mutemwia. Aside from his alleged role in re-establishing the Great Sphinx as a big tourist spot, Thutmose IV wasnt that notable of a pharaoh. He did, however, do a bit of building, especially at Amuns temple in Karnak, where he explicitly identified himself with the sun god Re. More on that later!   Sadly for young Prince Amenhotep, his dad didnt live very long, dying when his kid was about twelve. Amenhotep ascended the throne as a boy king, exercising his only dated military campaign when he was about seventeen in Kush. By his mid-teens, though, Amenhotep wasnt focusing on the army, but his one true love, a woman named Tiye. Shes mentioned as the Great Royal Wife Tiye in his second regnal year - meaning they got married when he was just a kid! Tip of  the Hat to Queen Tiye Tiye was a truly remarkable woman. Her parents, Yuya and Tjuya, were non-royal officials; Daddy was a charioteer and priest called the Gods Father, while Mom was a priestess of Min. Yuya and Tjuyas fabulous tomb was uncovered in 1905, and archaeologists found lots of riches there; DNA testing performed on their mummies in recent years has proved key in identifying unidentified bodies. One of Tiyes brothers was a prominent priest named Anen, and many have suggested that the famous Eighteenth Dynasty official Ay, alleged father of Queen Nefertiti and eventual pharaoh after King Tut, was another of her siblings.   So Tiye married her husband when they were both quite young, but the most interesting item about her is the way in which she was portrayed in statuary. Amenhotep deliberately commissioned statues showing himself, the king, and Tiye as the same size, showing her importance in the royal court, which was on par with that of the   pharaoh! In a culture in which visual size was everything, bigger was better, so a big king and an equally big queen showed them as equals.   This egalitarian portrayal is pretty much unprecedented, showing Amenhoteps devotion to his wife, allowing her to wield influence comparable to his own. Tiye even takes on masculine, regal poses, showing up on her own throne as a Sphinx who crushes her enemies  and getting her own Sphinx colossus; now, shes not only equal to a king in the way shes portrayed, but shes taking on his roles! But Tiye wasnt Amenhoteps only wife - far from it! Like many pharaohs before and after him, the king took brides from foreign countries in order to form alliances. A commemorative scarab was commissioned for the marriage between the pharaoh and Kilu-Hepa, daughter of the king of Mitanni. He also wed his own daughters, as other pharaohs did, once they came of age; whether or not those marriages were consummated is up for debate. Divine Dilemmas In addition to Amenhoteps marital program, he also pursued massive construction projects throughout Egypt, which burnished his own reputation - and that of his wife! They also helped people think of him as semi-divine and created money-making opportunities for his officials. Perhaps more importantly for his son and successor, the Heretic Pharaoh Akhenaten, Amenhotep III followed in his fathers sandalprints and identified himself with the biggest gods of the Egyptian pantheon on the monuments he built.   In particular, Amenhotep placed great emphasis on sun gods in his construction, statuary, and portraiture, displaying what  Arielle Kozloff aptly called a solar bent in every aspect of his realm. He showed himself as the god of the sun at Karnak and contributed extensively to Amun-Res temple there; later in life, Amenhotep even went to far as to consider himself as a living manifestation of  all  deity, with an emphasis on the sun god Ra-Horakhty, according to W. Raymond Johnson. Although historians dubbed him the Magnificent, Amenhotep went by the moniker of the Dazzling Sun Disk. Given his fathers obsession with his connection to the solar gods, its not too far of a stretch to get to the aforementioned Akhenaten, his son by Tiye and successor, who declared that the sun disk, Aten, should be the sole deity worshipped in the Two Lands. And of course Akhenaten (who started his reign as Amenhotep IV, but later changed his name) stressed that  he, the king,  was the sole intermediary between the divine and the mortal realms. So it looks like Amenhoteps emphasis on the   godly powers of the king went to an extreme in his sons reign. But Tiye may have also set a precedent for her Nefertiti, her daughter-in-law (and possible niece, if the queen was the daughter of Tiyes putative brother Ay). In the reign of Akhenaten, Nefertiti was depicted as occupying roles of great prominence in her husbands court and in his new religious order. Perhaps Tiyes legacy of carving out a great role for the Great Royal Wife as partner to the pharaoh, rather than mere spouse, carried on to her successor. Interestingly, Nefertiti also assumed some kingly positions in art, as her mother-in-law did (she was shown smiting enemies in a typical pharaonic pose).
