STRAIT OF GIBRALTAR

STRAIGHT OF GIBRALTAR

STRAIGHT OF GIBRALTAR
Over 100,000 ships transit through Gibraltar every year

Density of seawater in the Strait of Gibraltar One of the unique features of the Strait of Gibraltar is the inflow and outflow of the Medย  which consists of layers of water with different salinity (salinity). Atlantic water is less saline and less concentrated than Mediterranean water, and flows eastward into the Mediterranean through straits as a surface layer, flowing at a speed of 2 to 3 knots at a depth of about 125 m. In contrast, heavier, cooler, and saltier water flows westward into the Atlantic Ocean. Depending on the phase of the tide, the currents flow eastward faster or slower.

 

 

Tides in the Strait of Gibraltar โ€“ย 
A very distinctive feature of the Strait of Gibraltar is the continuous evaporation of water. Vertical water height in the Mediterranean Sea decreases by almost 1 meter every year. About 6.5+ million years ago, the general shape of the Mediterranean base was similar to what it is today. The movement of the plates cut off the flow of water from ocean to ocean, completely evaporating the area. But about 5+ million years ago, the plates moved again and the straits opened, allowing large amounts of water to flow out of the ocean and refill the Mediterranean basin. This evaporation continues today, and it is estimated that if the strait were to close at current high sea levels, the basin would evaporate again. Backwash and Internal Waves Adding another challenging piece to the tidal puzzle that shapes the Strait of Gibraltar near the African continent are the often narrow two-knot backwashes that interact with the Caminal Stile (the shallowest part of the strait) and cause internally generated waves. As stated by NASA; "The waves are generated when daily tidal pulses flow through the shallow Caminal Stile near Gibraltar. They flow eastward and break up the coastal topography. They can be traced up to 90 nm, and in some cases produce interference patterns due to refracted waves

Internal waves are vertical movements between two layers and can have displacements of over 100 m with wavelengths of 1-3 nm. They are so noticeable as surface wave patterns that sunlight is carefully scattered by the water surface


Alboran Gyre

As the upper-level flow pours into the Mediterranean, the Coriolis force (an effect of the earth's rotation) causes it to form a large clockwise eddy (gyre) off the North African coast called the Alboran Gyre. A smaller weak anti-clockwise eddy forms to the North. Countercurrents (westward direcction) can be seen close inshore along both shores, particularly near headlands that project into the current.

The western end of the Mediterranean, akaย  Alboran Sea, is the habitat for aย  largest population of dolphins in the western Mediterranean

A layer of outward-flowing dense water stays deep after exiting the Mediterranean and forms a ribbon extending along the Spanish and Portuguese coasts at about 1000m depth.

ROCHAMBEAU 2024-05-05ย  account from SV ROCHAMBEU

Beyond devastated. Thatโ€™s how we feel right now. Itโ€™s been a while since Iโ€™ve really documented our nomadic lifestyle. We have sailed from California, USA through Mexico, Costa Rica, the Pacific side of Panama, through the Panama Canal, the Caribbean side of Panama, through Colombiaโ€™s โ€œpirate alleyโ€, and two thirds the way to Aruba, actually into the waters of the Netherland Antilles. We met some of the most amazing adventurous people along the way who will forever be in our hearts. Some of them we met in California and others in Mexico. Some have split up but then we meet back up and call it โ€œbungee-boatingโ€. Some we will never see again. But yesterday morning we split up unexpectedly, heart wrenchingly. After motor sailing for 2 days and 2 nights in benign sea conditions, the weather took a drastic turn. Suddenly while on night watch, 25 knots of steady wind came out of the Atlantic and the seas starting pounding. By daylight we were feeling drained from a lack of sleep and our buddy boats had begun drifting away. We were still fine, all communicating on VHF radio, and eagerly waiting to just get through it for another 40-50 miles so that we could wake up to sunny Aruba and eat an anticipated Dutch breakfast. (You shouldโ€™ve seen how excited Rolf grew a few nights ago when it dawned on him that we were going to sail to a country where people spoke his language and he could eat Dutch food again.) But then suddenly a new tie down strap for our dinghy snapped and blew away. Shit! Because we were bashing there was a lot of force and our dinghy davits were compromised, now damaged and weakened. We had another new strap and were able to secure the dinghy. Good. But, our solar arch is also partially sitting on top of the davits and now the dinghy and solar panels are at risk of just breaking off and going kerplunck into the angry ocean. If that werenโ€™t enough, we had a 2 knot current that we were fighting against while feeling like we were riding a bucking bull. This slowed us down to a whopping 1 knot of โ€œspeedโ€. We were crawling and waves were crashing over our bows every now and then. Making life go from worse to miserable, our autopilot shutoff because it couldnโ€™t keep up with the bashing. Conditions matter. And yesterday morning was a perfect example where with rough seas, strong current, and high wind (all on the nose) was a trifecta for poor motor performance and loss of the autopilot. So we had to make one of the toughest decisions ever - either steer by hand for 2 days and crawl to Aruba or turn back to Colombia. The main considerations were the stability of our dinghy davit system, our own safety & fatigue, and the comfort of our 14 year old dog, who was clearly suffering too. We bashed for an hour debating back & forth whether we could make it safely to Aruba or turn back. The problem was that the weather forecast now indicated the wind and sea state could persist for another couple of days. So with immense sadness we turned around. ๐Ÿ˜ญ๐Ÿ˜ญ๐Ÿ˜ญ Now weโ€™re alone, sailing back down the Colombian coast to Santa Marta, maybe even back to Cartagena. Next up, we have to still work our day jobs, which can be stressful and demanding at times while we figure out how to reinforce our dinghy davits and consider replacing our props. Really, I wish we could buy a bigger and more powerful boat with tons of horsepower for the 5-10% of the time we really need to motor hard from one amazing destination to another. But for now, Iโ€™m back to the night watch cruising solo. At least weโ€™re comfortable with the wind and swells behind us and our sails are up.

THE WINDWARD PASSAGE

WINDWARD PASSAGE

THE WINDWARD PASSAGE

Windward Passage Windward Passage, the NE approach to the Caribbean Sea, lies between Hispaniola and Cuba, 45 miles to the NW. The channel is free from obstructions and no special directions are necessary if both coasts are given a wide berth. Tidesโ€”Currents.โ€”The set through the Windward Passage is SW in mid-channel at a rate which is usually less than 0.7 of a knot, but may attain rates of 2 knots. Near the coasts on either side of the passage, tidal currents are strong and irregular. On the E side of the passage, a current sets N at a rate of 0.7 knot around Pearl Point (19ยฐ40'N., 73ยฐ25'W.), but 6 miles off- shore the current will set W or WSW. Close N of Cap du Mole St. Nicolas, the N current meets a constant set flowing along the N coast of Hispaniola and causing ripples. The W flow from Cap Haitien through Chenal de Tortuga, at a rate of about 1 knot, sets between Rabal and Cap du Mole St. Nicolas.
