Observatory Inlet

Observatory Inlet is a science topic covered in the lgStudy science library. This page brings together a partial reference excerpt, illustrations, worked examples, real-world applications and a short study plan, so you can understand Observatory Inlet rather than just read about it. In short: Observatory Inlet is an inlet on the North Coast of British Columbia. It is a northward extension of Portland Inlet, other branches of which include the Portland Canal.

Key takeaways

  • Observatory Inlet belongs to science; place it in that map before memorising details.
  • Learn the definition first, then one example that makes the definition concrete.
  • Connect Observatory Inlet to a quantity you can measure, compute or draw — that is where exam questions come from.
  • Reproduce the core statement of Observatory Inlet from memory before moving on to harder problems.

Reference excerpt

Observatory Inlet is an inlet on the North Coast of British Columbia. It is a northward extension of Portland Inlet, other branches of which include the Portland Canal. The entrance of Observatory Inlet, from Portland Inlet, lies between Ramsden Point and Nass Point. Ramsden Point also marks, to the west, the entrance of Portland Canal. The Nisga'a assert that the inlet constitutes part of their ancient territory.

Features Ksi xts’at’kw/Stagoo Conservancy The 11,647 ha (28,780 acres) conservancy was designated in Spring 2006, access to the conservancy is primarily by boat with a good anchorage in Stagoo Inlet. The Nisga’a have historically collected food and materials from Ksi Xts’at’kw/Stagoo, the conservancy is also part of the traditional territory of the Metlakatla. Observatory Sill A 60 m (200 ft) aquatic sill divides Observatory Inlet from Portland Inlet, tidal flows over the sill are known to be energetic and capable of producing internal waves, hydraulic jumps and other internal disturbances.

Etymology Observatory Inlet was named by George Vancouver in 1793, because he set up his observatory on the shore of the inlet, at Salmon Cove, in order to calibrate his chronometers. His two vessels, HMS Discovery and HMS Chatham, stayed in Salmon Cove from July 23 to August 17, 1793. During this time a boat surveying expedition under Vancouver himself explored Behm Canal. Vancouver also named three headlands at the entrance of Observatory Inlet: Maskelyne Point, for Nevil Maskelyne, the Astronomer Royal, Wales Point, for William Wales, the mathematical master who sailed with James Cook, and Ramsden Point, after the famed mathematical instrument-maker Jesse Ramsden.

Geography Observatory Inlet has two main arms, the northwest and longer one being named Hastings Arm, fed by the Kshwan River, and Alice Arm, an east arm, fed by the Kitsault River. Hastings Arm is approximately 30 km (19 mi) in length, and runs on a nearly true north–south axis, Alice Arm is approximately 25 km (16 mi) in length and bends sharply, running on a roughly northeast–southwest axis. From their merger to the mouth of Observatory Inlet is approximately 50 km (31 mi) in length, running south-southwest to its merger with the Portland Canal just southwest of Nass Bay, which is an arm of Observatory Inlet and the saltwater outer estuary of the Nass River. Of many islands in the inlet, Granby Peninsula and Brooke Island are located at the intersection of the Hastings and Alice Arms. Granby Peninsula and Granby Bay are named for Granby Consolidated Mining, Smelting and Power Company, which built and operated the mining town of Anyox, located on Granby Bay.

Settlements At the aperture of Nass Bay is the community of Arrandale on its southern point, with the community of Ging̱olx (Kincolith) located on its northern shore just inside the bay at the mouth of the Kincolith River. Also entering the Nass estuary just to its east is the Iknouk River. The smelter ghost town of Anyox is located on the west side of the inlet at Granby Bay, which marks the beginning of Hastings Arm. The locality of Alice Arm, which is a former steamer landing and on the west bank of the mouth of the Kitsault River, is located at the head of the inlet's Alice Arm projection. The former mining town of Kitsault is located 2.5 km (1.6 mi) due south of Alice Arm, on the far side of the inlet's shoreline. With no rail nor road connection to the rest of British Columbia, these mining towns relied on shipping through Observatory Inlet. Adjacent to the community of Alice Arm, but on the east side of the Kitsault River, is the Nisga'a village of Gits'oolh (formerly Gitzault Indian Reserve No. 24).

Worked examples

Example 1 — a first encounter with Observatory Inlet

Start with the simplest possible case. Write down what Observatory Inlet claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In science, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to Observatory Inlet before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about Observatory Inlet ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of Observatory Inlet

In research
Observatory Inlet appears in science research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry
Engineering practice reuses Observatory Inlet in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom
Observatory Inlet is common in secondary-school and first-year university syllabi. It links to neighbouring topics Fjord stubs, Fjords of British Columbia, Inlets of British Columbia, so understanding it makes those chapters shorter.
In everyday life
Look for Observatory Inlet outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.
