This depends on how you define noteworthy. To me, as someone with a strong interest in WWI naval history, every single battle, right down to the tiny ones that were basically a few motor boats shooting at each other, is noteworthy. But for the more general student of the war, there are still other noteworthy battles beside Jutland. Yes, Jutland was the only engagement between the British and German battlefleets in their entirety, but there were smaller but still significant battles. The typical English-language history of the naval war will identify five major battles between the Royal Navy and the German Navy, of which Jutland is just one. There were also two significant battles between the German and Russian navies. Finally, there were two long-running campaigns in which naval forces played a significant part - the First Battle of the Atlantic, and the Gallipoli Campaign.

The first of these naval battles came on the 28th August 1914. Commodore Roger Keyes, commanding a submarine flotilla based at Harwich, had been running patrols off the German coast. His commanders noticed that the German patrols in the Heligoland Bight followed a strict schedule that left ships vulnerable at particular times of the day. Keyes and Reginald Tyrwhitt (commander of the Harwich Patrol, a surface force), hatched a plan to ambush these ships. The Admiralty approved the plan, but added a force of battlecruisers under David Beatty to Keyes' and Tyrwhitt's light forces, though they failed to properly notify Tyrwhitt. The battle started at about 7 am on the 28th, when one of Tyrwhitt's light cruisers, the Arethusa, sighted a German destroyer. The ensuing battle was a confused melee, with poor communications dogging both sides - the British had issues with misidentifying ships, while the Germans had no idea of the scale of the battle. The British managed to ambush the German destroyers, sinking one, before being driven off by the arrival of German light cruisers. However, when Beatty's battlecruisers (and their supporting light cruisers) arrived, the British were able to smash the German force. The British suffered heavy damage to three destroyers and one light cruiser. In return, they sank three light cruisers and a destroyer, and heavily damaged another cruiser and three more destroyers. The light cruiser losses were particularly significant, representing a quarter of those available to the High Seas Fleet HSF, the main German battlefleet). The Battle of the Heligoland Bight was seen as a major victory in Britain, though the RN was disappointed that it was unable to do more damage. On a broader strategic level, it was a strong contributor towards the passivity the HSF displayed during the war, and helped create a situation where the war in the North Sea was dominated by lighter forces rather than by the battlefleets.

The next major battle came not in the North Sea, but off the coast of South America. In peacetime, the Germans maintained a strong squadron in the Far East, at its Chinese colony of Tsingtao (now Qingdao) and in its Pacific islands. This force, commanded by Admiral Maximilian, Graf von Spee, had two armoured cruisers, Scharnhorst and Gneisenau, and three light cruisers at the start of the war. When the war started, von Spee, aware that Tsingtao and Germany's Pacific colonies were vulnerable, wished to return to Germany. To avoid the strong Allied forces in the Indian Ocean, he headed eastwards, crossing the Pacific, though he did detach one light cruiser, the Emden, to raid the Indian Ocean and West Pacific. As he neared South America, he was joined by another light cruiser, the Dresden, which had been representing German interests in Mexico. Meanwhile, a British squadron, under Rear-Admiral Christopher Cradock, was patrolling the region. Cradock had two obsolete armoured cruisers, Good Hope and Monmouth, a light cruiser, Glasgow, and the armed merchant cruiser Otranto (he also had an obsolete battleship, the Canopus, but had detached her due to false reports of engine issues). The two forces engaged each other off the Chilean port of Coronel on the 1st November 1914. Cradock's force, outclassed and outnumbered, was soon battered into submission. Monmouth and Good Hope were sunk, with little damage caused to any German ship. Glasgow and Otranto fled. This was the first time the RN had lost a battle since the War of 1812.

Naturally, the RN was outraged by the Battle of Coronel. Two battlecruisers, three armoured cruisers and a light cruiser were dispatched southwards, under the command of Doveton Sturdee. They rendezvoused with the remains of Cradock's squardon at the British coaling station at Port Stanley in the Falklands Islands. The next day, von Spee's squadron arrived at the Islands, hoping to seize the coaling station, allowing him to use the coal to refuel his ships and to deny it to his pursuers. While Sturdee's ships were unready for a fight, they soon got steam up and gave chase. Sturdee's faster battlecruisers managed to catch the German armoured cruisers, and with their heavy armament, destroyed them, while taking little damage. The British light and armoured cruisers, meanwhile, chased down the German light cruisers, sinking two. Only Dresden managed to escape, though she would later be caught and sunk at the island of Mas a Tierra. The Battle of the Falklands was a strong demonstration of the power of the battlecruiser, and a fine revenge for the RN's loss at Coronel.

While this drama had been playing out, the German HSF had been carrying out raids against the British coast. Hoping to bring out parts of the RN's Grand Fleet which could be defeated in detail, battlecruisers were used to bombard British ports and coastal towns, while the HSF lurked in the offing. These operations brought little success - little damage was done to the coastal towns, and the Grand Fleet was not engaged. The commander of the German battlecruisers, Franz Hipper, feared that the British had gained advance warning of these raids from spy trawlers mingling with the fishing fleets on the Dogger Bank. He planned an operation to search these fleets for suspicious vessels, and set out to do so on the 23rd January 1915 with three battlecruisers and the semi-battlecruiser Blucher. In fact, the RN did have advance warning of German operations, but this came from signals intelligence. This allowed them to dispatch Beatty's force of five battlecruisers to catch Hipper. Beatty caught Hipper on the morning of the 24th. Hipper almost immediately turned to flee, leading to a running battle. Heavy damage was done to ships on both sides. The German Seydlitz nearly blew up following a turret fire, while Beatty's flagship Lion was nearly immobilised following a hit which allowed seawater to enter a fresh-water tank for her boilers. Blucher, at the end of the German line, bore the brunt of the British fire, and Hipper abandoned her to flee for home. While the British could have continued the chase, communication mishaps and a submarine scare meant that they abandoned it to concentrate on the Blucher.

1915 also saw the Gallipoli Campaign, which saw significant naval involvement, especially in the early stages. I've covered this in detail here. The other main naval campaign was the First Battle of the Atlantic, the Allied defeat of the German anti-shipping campaign using U-boats, which I've described here.

In the Baltic, meanwhile, the German fleet attempted to cover landings in the Gulf of Riga. This saw a relatively inconclusive naval battle between the Russian and German fleets, while the battlecruiser Moltke was damaged by a torpedo from the British submarine E1. While little damage was done on either side, the Russians did prevent the Germans landing. The other main battle in the Baltic came in 1917. The Germans were trying to seize the islands at the entrance to the Gulf of Riga, in Operation Albion. Successful landings were carried out in September 1917, allowing the Germans to force a battle with the heavily outnumbered Russian ships remaining in the Gulf. The German force sank the pre-dreadnought Slava, and the destroyer Grom.
