A walk with the elephant seals at Año Nuevo

A few weeks ago I had the good fortune to join my Aquarium kids on our field experience to Año Nuevo State Park, the home of approximately 10,000 northern elephant seals. I get to do this trip every two to three years old and I love it every time. We tend to visit Año in January because that is the height of the pupping and breeding season. 

There is a lot happening on the beach at this time. The biggest, experienced males (aka the beachmasters) establish dominance when they arrive and establish a large harem of females. Fights between males tend to break out when a beta gets a bit too close to the alpha male's section of the beach and the ladies on it. The fights are loud, sometimes bloody, and often result in females and pups being separated and sometimes crushed. These younger males on the edges of the harem are unlikely to take over the harem, but sometimes get lucky and manage to sneak into the harem and mate when the alpha male is not paying attention. Researchers only recently discovered these "sneaker" males were contributing to the gene pool much more than they thought. A bit further from the harem, juvenile males with no chance of establishing a harem or standing up to an alpha male, practice their fighting moves. The females give birth to a single pup a few days after they arrive at the beach and nurse their pups with milk that has 40% milk fat! For reference, human and cow milk is about 4%. Elephant seal milk is more like mayonnaise than milk. The pups put on about 10 pounds per day! While all this is going on, the colony is a noisy place. The seals have a wide range of squeaks, squawks, and snorts that give great pleasure to the humans watching them. 

The weather at Año is often anything less than stellar, so I went prepared with thermals, fleece, down vest, rain coat, and beanie. The day turned out to be spectacular, rendering everything but my base layer unnecessary. The skies were blue, there was no wind, and the temperature topped out around 65 degrees F. We were also really fortunate that our trip coincided with the king tides--the highest high tide (and lowest low tide) of the year. The high tide was just a couple hours before our tour reached the beach, so most of the seals were far up on the beach and very close to the viewing areas. We also had some close encounters with younger males that were lounging away from the main beach area.

While the docent guided us around the colony, we were supposed to stay at least 25 yards away from these giant animals. Looking at the 4,000 pound males, you would think that a quarter football field would be a pretty safe distance. If they are not happy with your presence, however, they can move FAST, so we tried to keep as much distance as possible. Most just opened an eye to make sure we were keeping our distance, gave us a snort, and then rolled over and went back to sleep. The seals can move quickly on land, but they definitely look a bit clumsy as they bounce along the beach. In the water, though, they are incredible swimmers and divers. When they leave Año in a couple months, the males will head off toward Alaska, while the females head out to the middle of the Pacific. They can dive to depths over 5,000 feet and hold their breath for almost two hours! They will come back to the beach again in a few months to molt and then go back to sea for 8 months before returning to the beach to start the cycle of pupping and mating all over again.

have to stay on the beach because they are too floaty to dive for food.

We are so fortunate to have these giants in our backyard. That wasn't a certain thing a hundred years ago. The northern elephant seals were hunted to near extinction for their blubber. In 1910, a remnant population of about 100 animals was found on Guadalupe Island in Baja California, Mexico. Protection by the Mexican government and subsequently the U.S. government allowed these animals to make a come back. They now number over 100,000 in California. During the government shutdown, they even took over some new real estate at Point Reyes National Seashore when rangers were not around to redirect them to a location less frequented by humans. Now that they have pups, the seals are there to stay and human access is being limited. 

You can find these giant seals in three mainland locations in California - Point Reyes, Año Nuevo, and Piedras Blancas at the southern end of Big Sur. If you are in central California between December and February, plan a visit to see these charismatic giants.

Starting the new year in Baja

We welcomed in 2019 from Zacatitos in Baja California Sur, Mexico. Our dear friends Christian and Lindsay invited us to stay with them at their family's place on the beach again this year. We joined them the first time in 2012 and really enjoyed our time there. When they asked us in September if we wanted to come down again this year between Christmas and New Years, we jumped at the chance. The timing of the trip worked well for Pete, a currently furloughed federal employee. It was a bit more tricky for me since I had just started a new job and had no accrued vacation hours. I worked extra hours to make up for our vacation time and my new employer was really understanding about our already scheduled holiday. 

We arrived in San José del Cabo in the early afternoon and were met at the airport by Lindsay and Arin. We then embarked on a scavenger hunt of sorts to find the tortillaria (where they make tortillas) and the carnitas (pan fried, slow-cooked pork) shop. We found the tortillaria but were coming up empty on the carnitas. Returning home without the carnitas may have caused a scene, so Arin asked some nice men for help. As it turned out, we were within blocks of the place and soon had two stacks of warm tortillas, two kilos of carnitas, and a giant piece of chicharrón (deep fried pig skin). We also grabbed two boxes of beer on our way home, which made our arrival at the house extra welcome. 

We spent our first full day in Baja diving in the Cabo Pulmo marine reserve. We got up early, drove two hours to Cabo Pulmo, and immediately put on wetsuits and hopped in the boat. The marine reserve was established in 1995 to protect some of the special marine species that live there, particularly the hard corals, which are the northern-most corals in the Sea of Cortez. Enforcement of the reserve has been challenging, though, so the benefits of the reserve have been spotty. Our first dive was at a site called Los Morros (the hills), which was an aptly named area of reef that undulated underwater. We saw lots of fish, mainly small individuals, lots of coral, some eels, and a couple Cortez round stingrays. 

When we surfaced from the dive, the wind had picked up and the sea was quite choppy. The water temperature was only 70oF, so I had gotten quite chilled during the dive with a 2 mm wetsuit and 2 mm shortie over the top. The wind at the surface was not helping me warm up, so I huddled on the bottom of the boat to get out of the wind. We had a short surface interval before hopping back in the water for our second dive on the ship wreck. The ship that sank wasn't very big and it was in many pieces. The draw for this site is the potential to see bull sharks. The site is relatively small, so we swam around it a number of times looking for cool critters and sharks. There were a few big fish at this site, which was nice to see. We didn't see any sharks, but there were lots of goat fish and conger eels - two of Pete's favorites - so all was well. The wind had picked up even more during our second dive, so we made a bee line for the beach and started the process of trying to warm up. Fortunately the sun came out at regular intervals to combat the wind that was still blowing. 

We spent the rest of our time at the house in Zacatitos reading, playing games, swimming, snorkeling, walking on the beach or in the desert, and watching humpbacks swim and splash and morbula rays leap out of the water. We also ate delicious food, made almost exclusively by Christian, who would often retreat to the kitchen at 2 pm to make all of us dinner. We were also treated to some phenomenal sunsets and sunrises, and a beach encounter with the local residents.

We left Baja fully relaxed and reveling in the time we had with good friends. We returned to cooler, wetter weather in California. While we welcome the rain, it could come in smaller doses. Last weekend the river jumped from 3.5 feet to 13.2 feet after four inches of rain, reminding us how quickly things change around here. We are expecting another round of storms this week so we've winterized the garage to be ready for any possible flooding this winter. Hopefully all will be for naught. 

Pete is still furloughed, which is frustrating and maddening. He is so ready to go back to work! Not quite the start to the year we were hoping for, but hopefully things will get settled soon. Sigh.

A visit to NZ

Leaving NZ was hard for me, but I knew I would be going back before the end of the year, so I had something to look forward to. I headed back to NZ in mid-November for a three week trip that was packed with comings and goings, mostly all work related. 

I spent my first week in Auckland back at the Auckland Council office handing over projects and programs to the new marine scientist and finishing the last few projects that were still outstanding. It was great to see everyone again but also hard to believe that I had been away from the office for four months. I timed my trip so I could join our team on their annual Christmas outing to Anawhata, one of the beautiful beaches on the west coast of the Auckland Region. It was really fun to have some time with the team away from the office. I also got to spend some really good quality time with a good friend and coworker, which was definitely the best part of my Auckland time.

The weather wasn't fantastic in Auckland, but the long summer days were great! I was able to get a run in nearly every day I was there either before or after work. There were some amazing sunrises that made getting out of bed early worth it.

I spent the second week of my trip about two hours south of Auckland in Hamilton working with a friend and colleague from NIWA - the National Institute of Water and Atmospheric Research. This was the main reason for my trip - helping to design and facilitate a national workshop on cumulative effects. I've been working on this project for the last few years and this workshop was the culmination of our work. It was a challenging workshop to design, but Kate and I had a lot of fun along the way. My week in Hamilton was great. I was staying at a place near the Waikato River, so I got to run on the river trail every day. I also got to do a bit of mural hunting and squeezed in a quick trip to the lovely botanic garden.

Our workshop was in Wellington, so we headed down there for a few days to start my third week. My morning runs were a bit rainy, but I found lots of murals close to our hotel. I also had a really cool encounter with some native birds in the botanic garden. I was running along and all of a sudden there was a whole bunch of squawking and commotion in a tree along the trail. I stopped and saw a tui (the two blue-ish birds in the mural below) fighting with a flock of kakas (large parrots - brownish bird in the mural below) that had descended on its territory. The tui was outnumbered six to one but it was not giving its tree up without a fight.

I spent the last few days of my trip in Nelson with my friend Robyn. She started building a house last year and the original timing was such that Pete and I had planned on being available to help Robyn with the interior of the house. The permits got delayed, though, so she didn't start building until after we left NZ. The timing of my trip was great because there were still lots of projects. The drywall had just been hung and mudded and the electrician wanted to get the lights and switches installed, so Rob and I were on painting duty. In three days, I think we painted 12 to 14 hours just to stay ahead of the electrician and the plumber. All that work paid off, though, because I got to be there when Robyn spent the first night in her new house!  

Even with all the painting, we did a lot of fun things too. We went for a long hike up the valley from Rob's place with the dogs, complete with a picnic and a post-hike swim. We took the horses out for a ride another day and swam in the river just about every day. And of course, we ate like queens. It was the perfect way to end my trip and I cannot wait to go back. 


The flax blossoms were a really different color on this hike. 
The soil in part of the area is very mineral rich (serpentine soil)
so it is possible these flax plants are adapted to the local conditions.

The Humboldt redwoods in our new-to-us Wish replacement

One of the most difficult things for us to part with when we left NZ was our car, the Wish called Wanda. The Wish was a Toyota that was smaller than a mini van but a bit bigger than a station wagon. There were three rows of seats and the back two rows folded flat. This made it a perfect vehicle for sleeping in when we didn't feel like setting up the tent or it was raining (our tent fly sprung a leak about four months into our time in NZ). She got about 32 miles to the gallon, which was great in NZ where fuel is about $8 per gallon.

Much to our dismay, when we returned to the U.S., we were having trouble finding anything that was very Wish-like. We could find vehicles with fold-flat seats, but they tended to be quite a bit larger with worse fuel economy. And then we stumbled upon the Mazda 5, which is nearly identical to the Wish. A friend of ours refers to their one as a "nano-van" which I think is a very apt description. We happened upon a used one in Santa Cruz and are now the owners of what we call the Wish 5. 

We took the Wish 5 for her inaugural trip in early November to the Humboldt redwoods. When we made our camping plans, we were mostly concerned about being rained out. That would have been a much better situation than the wildfires that were burning throughout the state. The Bay Area had been blanketed in wildfire smoke for about ten days prior to our trip and we were not sure what to expect for the weekend. The smoke forecasts were changing daily and were not always consistent with where the plume would be located. The air quality got worse as we drove north, but we managed to make it out of the smoke zone about 30 miles from our destination.   


all ready for sleeping

We live in a redwood forest, so it might seem crazy for us to drive five hours to spent the weekend in another redwood forest. However, the trees in Humboldt are HUGE compared to the babies we have down here so the forest felt quite different even though the trees are the same. The Avenue of the Giants is a spectacular drive with many hiking opportunities along the way.  

The Save the Redwood League is largely responsible for the existence of so many large, old growth redwoods in and around Humboldt State Park. In the early 1900s, the founders of the club noticed that the big trees were being logged for timber and development and knew that many more would be lost if they didn't do something. Since 1918 they have protected more than 200,000 acres of redwood forest, supported the establishment of numerous state and regional redwood parks, and funded research throughout the states redwood forests. 

giant trees!

The burls on redwoods (the bulbous bits) are important
for regeneration. Spouts can emerge from the burls when
new space opens up in the canopy or when the main tree
gets damaged or is stressed by environmental conditions.

their bases are hollowed out from fire


The Dyerville giant - this 371 foot giant fell in 1991. It is
almost easier to get a sense for the size of these trees
when the whole thing is on the ground.

We were mostly out of the wildfire smoke, but a few
particulates in the air made for dramatic lighting in the forest.

Our first two nights in the Wish 5 were great and we have a list of things to add to the car to make it even better. We're looking forward to more trips in the near future!
