The earliest signs of settlement go back to the 1600s, when a Maori (indigenous) clan lived in a fort at this site. By all accounts they were decimated by measles after the arrival of Europeans, who set up whaling and sealing stations on the beach below Taiaroa Head. In the 1840s those enterprises collapsed, and Maori and Europeans alike headed elsewhere, mostly to the newly established city of Dunedin. In 1919 the first royal albatross egg was found here, and so Taiaroa Head became a famous albatross colony. Sadly, there was plenty of distrust and violence between the Maori and European folks. Sources differ on what exactly happened between them, and how the disease measles was introduced. I'd encourage you to do a bit of reading on New Zealand heritage sites if you want to know more. Edit: The clan present from ~1600 onward is called Ngai Tahu, however they were not the first clan to inhabit this area, and they may have erased traces of an earlier settlement. A mystery for an aspiring archeologist, perhaps!
@ThomasStevensontutor, recent studies now show that there are now fifty-two extant genera of whales (order Cetacea), which therefore renders the genera Balaenoptera, Phocoena, Lagenorhynchus, Cephalorhynchus, and Stenella polyphyletic The Balaenoptera genus now contains only the Fin Whale (Balaenoptera physalus), the Phocoena genus now contains only the Harbor Porpoise (Phocoena phocoena), the Lagenorhynchus genus now contains only both the Hourglass Dolphin (Lagenorhynchus cruciger) and the White-Beaked Dolphin (Lagenorhynchus albirostris), the Cephalorhynchus genus now contains only the Heaviside's Dolphin (Cephalorhynchus heavisidii), and the Stenella genus is now restricted to only the two species of spinner dolphin being the Short-Snouted Spinner Dolphin (Stenella clymene) and the Long-Snouted Spinner Dolphin (Stenella longirostris) The all eight rorqual species that used to be classified in the genus Balaenoptera are now officially thought to be more closely related to the Humpback Whale (Megaptera novaeangliae) and are therefore relocated to four separate genera: Rudolphius for only the Sei Whale (Rudolphius borealis), Rorqualus for the Omura's Whale (Rorqualus omurai), Rice's Whale (Rorqualus ricei), Bryde's Whale (Rorqualus brydei), and Eden's Whale (Rorqualus edeni), Pterobalaena for the two species of minke whale being the Arctic Minke Whale (Pterobalaena acutorostrata) and the Antarctic Minke Whale (Pterobalaena bonaerensis), and Sibbaldius for only the Blue Whale (Sibbaldius musculus), with the blue whale of the monotypic genus Sibbaldius being the closest living relative of the humpback whale and the minke whales (genus Pterobalaena) being the second closest, the humpback whale, blue whale, and minke whales all constitute the subfamily Megapterinae, the sei whale of the monotypic genus Rudolphius and the omura's, rice's, bryde's, and eden's whales that constitute the genus Rorqualus all belong to the subfamily Rudolphiinae, which is most closely related to the Megapterinae subfamily, thus leaving the fin whale (Balaenoptera physalus) the most basal and distantly related from all the other extant rorqual species as it is also the only extant member of the subfamily Balaenopterinae, which is the most basal of the three rorqual subfamilies All the three porpoise species that used to be classified in the genus Phocoena are now officially believed to be more closely related to the white-waisted porpoises (genus Phocoenoides) and finless porpoises (genus Neophocaena) and are therefore relocated to two separate genera: Boreophocaena for only the Vaquita (Boreophocaena sinus) and Australophocaena for both the Burmeister's Porpoise (Australophocaena spinipinnis) and the Spectacled Porpoise (Australophocaena dioptrica), the Vaquita (Boreophocaena sinus), True's Porpoise (Phocoenoides truei), and Dall's Porpoise (Phocoenoides dalli) all belong to the subfamily Phocoenoidinae and the Burmeister's Porpoise (Australophocaena spinipinnis), Spectacled Porpoise (Australophocaena dioptrica), Indo-Pacific Finless Porpoise (Neophocaena phocaenoides), Yangtze Finless Porpoise (Neophocaena asiaeorientalis), and East Asian Finless Porpoise (Neophocaena sunameri) all belong to the subfamily Neophocaeninae, leaving the Harbor Porpoise (Phocoena phocoena) as the most basal and distantly related from all the other extant porpoise species as it is also the only extant species of the subfamily Phocoeninae, which is the most basal of the three porpoise subfamilies The dolphin species that used to be in the genera Lagenorhynchs, Cephalorhynchus, and Stenella are now relocated to seven genera Sagmatias for only the Peale's Dolphin (Sagmatias australis), Leucopleurus for the three species of white-sided dolphin being the Atlantic White-Sided Dolphin (Leucopleurus acutus), Pacific White-Sided Dolphin (Leucopleurus obliquidens), and Dusky Dolphin (Leucopleurus obscurus), the Leucopleurella for only the Chilean Dolphin (Leucopleurella eutropia), Orcasoma for both the Hector's Dolphin (Orcasoma hectori) and Commerson's Dolphin (Orcasoma commersonii), Plagiodon for only the Striped Dolphin (Plagiodon coeruleoalbus), and Spilodelphis for the two species of spotted dolphin being the Atlantic Spotted Dolphin (Spilodelphis frontalis) and the Pantropical Spotted Dolphin (Spilodelphis attenuatus), while belonging to the subfamily Cephalorhynchinae alongside the white-beaked, hourglass, and heaviside's dolphins, the peale's dolphin of the monotypic genus Sagmatias is the only surviving member of the tribe Sagmatiini, which is the most basal tribe of the subfamily Cephalorhynchinae, the chilean dolphin, hourglass dolphin, and white-beaked dolphin all belong to the tribe Lagenorhynchini, and the heaviside's dolphin, hector's dolphin, commerson's dolphin, and white-sided dolphins all belong to the tribe Cephalorhynchini, which means that the hector's dolphin and commerson's dolphin that both constitute the genus Orcasoma are more closely related to the white-sided dolphins (genus Leucopleurus), with the heaviside's dolphin of the monotypic genus Cephalorhynchus being basal to both, the chilean dolphin of the monotypic genus Leucopleurella is more closely related to the hourglass and white-beaked dolphins that both constitute the genus Lagenorhynchus, and the peale's dolphin that is the only extant species of both the genus Sagmatias and the tribe Sagmatiini is the most basal of the subfamily Cephalorhynchinae, both the striped dolphin (Plagiodon coeruleoalbus) and spotted dolphins (genus Spilodelphis) are more closely related to common dolphins (genus Delphinus) and bottlenose dolphins (genus Tursiops), all twenty-two dolphin species that have long beaks belong to the subfamily Delphininae, with the right whale dolphins (genus Lissodelphis) of the monotypic tribe Lissodelphinini being the most basal, then followed by the spinner dolphins (genus Stenella) of the monotypic tribe Stenellini, leaving the most recent split to be between the tribes Stenonini and Delphinini, the former is split into the subtribes Sousina for both the Fraser's Dolphin (Lagenodelphis hosei) and Humpback Dolphins (genus Sousa) and Stenonina for the Rough-Toothed Dolphin (Steno bredanensis), Costero (Sotalia guianensis), and Tucuxi (Sotalia fluviatilis) and the latter is split into the subtribes Plagiodontina for both the Striped Dolphin (Plagiodon coeruleoalbus) and Spotted Dolphins (genus Spilodelphis) and Delphinina for both the Common Dolphins (genus Delphinus) and Bottlenose Dolphins (genus Tursiops).
wow thank you, I will be back with my 12 year old soon, she loves rocks, like me..I found a beautiful stream and lake in Ireland, the rocks there are mesmerising i feel like I found gold but nicer because it doesn't give me fever, and nobody ever trys to steal my samples. There is another top secret beach that is my new favourite place in Ireland, full of amazing rocks, basalt cliffs, and other rocks, I am a beginner in learning, still at the wondering what they are all about stage, been at that stage for decades, anyhow, education is a great thing, and you sir have that in abundance, so well done. The beach I found has amazing abundance of sea fossils, marine fossils, and is abundant with mermaid purses, (shark baby pouches?) any way I feel nervous talking about this unspoilt beach with stunnng sand dunes cos, its too pristine and precious to share with the world
I'm a 36 year old guy who is going back to school for a change of profession. I am very grateful for videos like this. Physics if beautiful and by proxy so is chemistry. Thanks!
Sir according to Newton's third law Don't the electrostatic forces by each charge (independent of magnitude)cancel each other and don't move? Equal and opposite reaction?
When two charged particles are near each other, they each exert a force on each other. If they have the same charge, they repel and fly in opposite directions. In this case, there are two opposing forces that push the particles apart. According to Coulomb's Law (which I also made a video about) these forces have the same magnitude. If the two particles have opposite charges, they attract and stick together. In this case you still have two opposing forces, but they pull the particles together instead of pushing them apart. Again the two forces have the same magnitude. So yes, Newton's third law does apply, but it doesn't mean the forces between charges cancel out. If you look for my video on Coulomb's Law, hopefully it will make everything clear. :)
Hello! When a charge experiences electrostatic force, the force will cause it to move, just like pushing and pulling forces cause people and objects to move. That is unless some other force (like magnetism) is holding the charge in place. Hope this helps!
Good evening! I like ferrets too, as it happens, looking forward to meeting one some day. :P I'm from the deep south of New Zealand, where people do tend to sound a bit British. The stereotypical Kiwi accent comes from Auckland and the other big cities up north. I also speak French a lot, which may have affected things.
very informative video. can you please make a lecture series on deep water seismic sedimentology/seismic sequence stratigraphy and deep water depositional system.
Great question! The tail is not as dense as it may appear. It is made of heaps of tiny ice and rock particles, mostly the size of sand grains, that are spread out over a great distance. From Earth the tail looks dense because those particles are very shiny and reflect light toward us, which prevents us seeing through the tail. In reality it is more like a fog, and you've probably seen how far fog can stretch. :) Hopefully another viewer will provide a better answer in the replies...
Dear sir , i think meteorite s have a future , i think forgien planets are here allready , i want to be very good at finding meteorite s. How eggactly would you go about finding a dozen meteorite s? ( I like to compare an contrast ). I have found that digging sucxx , how do i find fresh meteorite s and on top ? How would i find old sand traps...beaches an rivers , now abandoned ? ... Bravo ! See ya !
Not trying to be rude by pointing this out, but the birds from 0:34 - 0:39 and 0:51 - 0:55 are actually Dunnocks! They're another type of European bird, a type of Accentor, that could very well be mistaken for a House Sparrow hen unless you know exactly what you're looking at. Great vid btw, loved how you highlighted the nest material collection tendencies of Sparrows lol
Not rude at all, thank you for pointing that out! In my defence I have very bad eyesight. :P I spent ages trying to locate an actual nest, but there were none in a spot I could actually film. This was the best I could manage. :)
