Can you maybe put circles around Rio de la plata and Lake Maracaibo? I didn't even see that the former one was on the map until the time was out. :-/

Great quiz otherwise! I still have a lot to learn.

That would definitely be good. I got Rio de la Plata when I saw the Estuary category, but I missed Maracaibo.

Level 82
Feb 2, 2021
This is great but a lot of them are very small and hard to find, hopefully we can get some dots/circles to make them visible

Level 75
Feb 2, 2021
Surely there should be a Southern Ocean included in such an in-depth quiz?
+1
Level 78
Feb 2, 2021
Rio de la Plata is a River, not a Sea. Rio means river in Spanish
+2
Level 82
Feb 2, 2021
Wikipedia: "Depending on the geographer, the Río de la Plata may be considered a river, an estuary, a gulf or a marginal sea." Similarly "The Gulf of Carpentaria is a large, shallow sea ..." Gulf/sea is often a matter of convention. Adriatic sea could be easily named a gulf.

I guess Dead Sea is too small to be included? And same for the Bay of Fundi (which has the highest tides in the world, but is small)?

Please just accept "English" for "English Channel". It doesn't seem right that you have to type th body of water for this one when you don't on every single other body of water.

Level 68
Feb 19, 2021
You don't have to type both. It accepts "Channel", as it should.

Level 71
Apr 26, 2021
Should accept 'English' for the English Channel, that is it's name, same as Mozambique Channel and others named for the nearness such as, Irish, Norwegian, Philippine, Alaska, California, Finland, Mexico, Maine, Oman, Panama, Thailand etc etc
+1
Level 82
Feb 7, 2021
I get that this isn't definitive, but I feel at least all the oceans should probably be included. Although I suppose this map kinda misses it - it only goes to about 55°S and the Southern Ocean starts at 60°S.
+2
Level 79
Feb 8, 2021
It isn't accepted by everyone as an ocean, guess the maker of the quiz included?
+1
Level 79
Feb 21, 2021
After the edit, I think the issue is that the map doesn't extend to Antarctica - because the cited source has the Southern Ocean and various Antarctic Seas around the ice shelves.

Can you accept "English" for English Channel?

Level 68
Feb 19, 2021
You really shouldn't. I know English people loving slapping their name on things that they don't own, but that doesn't mean we should indulge it.
+7
Level 71
Feb 19, 2021
Obviously your Anglophobia is showing ........you do not mind the 'Norwegian Sea' / Mozambique Channel / Irish Sea / South China Sea / Philippine Sea / Gulf of Panama / Java Sea / Gulf of Oman-Thailand-California / Indian Ocean etc etc.
+1
Level 68
Feb 20, 2021
I'm not at all an Anglophobe! I've lived in London twice, and even worked for Her Majesty's Government in the Foreign Office. It's just that in almost every language, this clearly shared sea is know by some variation of "La Manche", "La Mancha", "der Ärmelkanal". Even in Dutch, it's just called "The Channel" (Het Kanaal). It's literallly just the English who feel like they have to slap their name on this, and even in English, the operative word is clearly "Channel", not "English". When you call it "the Channel", people will know what you mean, and there won't be any doubt as to which channel is meant. When you call it "the English", people will have no idea whatsoever what you're talking about.
+4
Level 74
Mar 1, 2021
@dunkinggandalf2 It's not about anyone calling it "the English." It's about adding a less labour-intensive type-in, and moreover one that is consistent with the rest of the channels appearing in this quiz that do not require typing 'channel' after their names. No one calls it "the Oman" or "the Philippine" etc. yet I can type Oman and Philippine in for those channels. Feel free to dispute whether or not it should be called the English Channel, but that's got nothing to do with what people are requesting.
+1
Level 93
Apr 28, 2021
If you really knew the answer you would type Channel and get it right; no need to type English and not quicker as it has the same number of letters.

Huh. I've been bathing in the Celtic sea in Brittany every summer for all of my life, and I had no idea! I knew it was the Atlantic ocean, obviously, but I also knew that portion as the "Mer d'Iroise", which, it turns out, is a part of the Celtic sea. Who knew!
+2
Level 68
Feb 19, 2021
i've never heard anyone in the UK or Ireland, or Cornwall for that matter, refer to the 'Celtic' Sea. Anyone out there from the southern counties of Eire call it that?
+2
Level 68
Feb 20, 2021
I haven't heard it in Brittany either, but it's probably not an everyday name anywhere, since, if you've live by the sea, you're more likely to call it "the sea" anyway, without bothering to name it - hence my surprise. But I've looked it up, and it is indeed real, and you better believe I'll be using it regularly from now on!

Great fun. I only got around 40 answers but I learnt a lot. Wild guesses like "Norwegian" and "Greenland" were especially satisfying to see pop up as correct answers!

Level 71
Feb 19, 2021
Quite a tough one. I didn't know many of the seas/gulfs/straits around Indonesia/New Guinea/Australia. Also, I typed in "East" and it gave me the Sea of Japan, so I got confused and thought that it was the same as the East China Sea :P

I would buy the explanation for accepting just "channel" but not just "english" for the English Channel if it were the only one, but it's not. The only way to distinguish, then, is to be specific. The specific part is "english" not "channel." So, as with all other answers, the specific part alone should be accepted.

Hi there! I would like to use this map together with 'country borders' but I can't just 'put them together'... any idea how I could do that? And if I manage that can I use the map to create quizzes?
