Do water molecules “surf” the waves?

It seems like water molecules might follow the path of a wave given what we know from the water cycle.

Water-Cycle-Art2A

But, if you watch a floating object like a toy boat on a wave in the open sea it won’t travel with the wave but rather bob up and down. The water molecules are actually swirling under the waves helping to move energy to the wave. This swirling motion is known to oceanographers as the “circular orbital motion”.

Waves are mostly moved by wind. The water molecules in waves of the open ocean are not traveling along with the waves but rather under the waves in a circular motion.

When you get closer to the shore the orbital motion is non-existent because the waves touch the bottom. That phenomenon helps when you lose your boogie board in the surf zone.

10 best in the past nine years

Sometimes it’s nice to look at the past and see what’s worked. From the past nine years of posts on Beach Chair Scientist, it seems that one post has been the “most valuable player”. 100 ocean quotes is a surefire “make you stop by BCS for the first time and join the mailing list” kinda post. It’s the Wayne Gretzky, Babe Ruth, or Micheal Jordan in terms of stats. All other posts just fall short. But in the ethos of sportsmanship, here are ten posts that also bring some well deserved worth to this little blog. Which one are you rooting for?

My awesome, overprotective mom and horseshoe crabs

limuluslove_beachchairscientistwebNo joke. I like horseshoe crabs, but not more than my family. Especially my mom. Let me tell you a story about how incredible she was one particular evening in early June. It was probably about 2002 and I was a seasonal employee for the NJ Division of Fish and Wildlife. The job was awesome in every sense. Except the hours … either really early for tagging stripers along the Delaware Bay or really late to survey HORSESHOE CRABS!

In case you haven’t heard watching the horseshoe crabs come up to the wrackline to spawn is an incredible experience (check out my post on the short and sweet of horseshoe crab spawning here). You might see some Limulus polyphemus the nights near a full moon or new moon right as the sun is going down. But, it’s not until the tide is at its highest point that the ancient fossils really come out of their hiding spots. 2.IMGP1651-Photograph-James-Bulley-1024x680My co-workers and I went about as normal for this event and used the  quadrat to estimate the amount of females and males every six steps (the females are much bigger!). We’d log the numbers on a clipboard. After the length of the beach that was our responsibility we’d head home. It was about 2am one particular morning when we finally made it back to the van. I also worked as a waitress in the summer so it had been a long day. The data sheet was my responsibility. It blew away. It’s really windy by the sea usually!

We didn’t fudge any numbers. I went back the next night … but, not alone. My amazing, overprotective mom came with me. After all, I had to drive about an hour to a small town along the Delaware Bay in the middle of the night. It was going above and beyond. I mean, she’s not a nature-type so this was in pure mama bear mode that she made the trek with me. It was incredible … my mom was totally amazed by the phenomenon too. One minute there were about fifteen horseshoe crabs and the next hour as soon as high tide occurred they were covering the beach! That night I was able to share my love of teaching and horseshoe crabs with someone I loved. She exuded such enthusiasm that I have no doubt it’s one reason I keep this blog and it’s focus of all things horseshoe crabs going. She might have been pulling my arm and thought the whole experience was really gross and icky, but parents know how to let their kids shine and that’s just fine with me.

NOAA’S Ocean Today provides a great view of the field experience, too. Yes, I did wear a headlamp like those citizen scientists.

What gives a beach its unique features?

cfiles45766

Tides. Winds. Waves. You might think of those right away when you ask yourself “Why are beaches so different from one another?” The story of how and why beaches are unique is more than what we witness while lying in a beach chair watching the tide go out hour by hour. The personality of a beach actually started long before … depending on what type of activity occurs near it.

If a beach is on a coast with a lot of earthquakes and volcanoes than it means that coast is active. Active coasts are going to be rocky, jagged, and edgy. Think “lots of cliffs”. This is easily seen along the West coast of the U.S. On the other hand, a beach might have a gentle slope with dunes leading to the sea. Think “the picture above”. There may be earthquakes but they’re rare and no volcanoes. This would mean the coast is passive. Being an active or passive coast is the foundation of a beach. Almost like its genetics or DNA.

active_passiveSo what gives a beach its true character is what it relates with on a daily basis. Just like the people and media we interact with on a daily basis shape our true character. For instance, does a beach have an expansive estuary nearby? Does a beach have an energetic or dormant volcano nearby? If this is the case the coast would also be considered primary. Primary coasts have been created by land based factors such as drowned river valleys, glaciers, or volcanoes. On the other hand, the ocean can play an important role in shaping a coast as well. Maybe there is considerable wave erosion lapping the shore? Are coral reefs, barrier islands, or other marine depositions nearby that helped to form a shoreline? These coasts are called secondary.

Beaches are either on a passive or active foundation and each have prevailing short term factors of primary (land based erosion) or secondary (ocean based erosion). The combination of characteristics give each beach a distinctive quality. Just like each one of us each beach is valuable and precious.

Millions of smiles for miles at the #womensmarch

49b02a578bdcc86ebe96ffad6711045aI am proud of the way the Women’s March in D.C. was planned and executed. It was thrilling and invigorating to be with the droves of people who wanted their voice to be heard. I chatted with folks from North Carolina, Maine, and even Nevada. It was peaceful, fun, and loud at times. It made my feet hurt but I didn’t notice. I was joyful to be a part of it. I was there vibrant and strong with a chanting voice for equal rights for all those in this great country.

And, as a marine science enthusiast/ocean conservationist I was VERY hyped to many signs reminding the new administration of the reality of science and climate change. There will be more to come in posts this year urging for action for climate change. Maybe not a shout out to the federal government but for more grassroots changes. If there is one lesson learned from 2016 it’s that everyone should make more conscious choices in our daily actions – what we believe, read, share on social media to what we eat matters! For now here is a short film on some highlights from the day. Please share your favorite march moments below!

Seven silly sea science words

Somewhere along the line people got the idea that science is scary and intimidating. But, like so much of this world … science is much more than what we first think. Science can be silly. Science can be fun. Science can be collecting and analyzing data. But, science is creating questions. And, science is sharing results.

Science can even make you smile. To prove it – here are some silly sounding words that make me laugh every time I say them. I actually had to have my daughter narrate this short film because “caudle peduncle” is just too much sometimes. Hopefully this clip will make you curious to explore new words and realms within science. It’s bound to make you smile at least! By the way, do you have a favorite sounding sea science word?

Christmas critter countdown: Harp seal

This is the fluffy creature that tugs at our heartstrings and purses to fork over donations. What should you do though if you see a seal coming up on shore and lounging like he doesn’t have a care in the world? Or, if they’ve somehow lost their adorable, cute white fur and are a patchy?
