dari pada planet kita sendiri,
a new type of robot
jenis robot yang baru
better understand our own planet.
lebih mengenal planet kita sendiri.
as an unmanned surface vehicle, or USV.
sebagai Kendaraan Nirawak Permukaan, USV.
on wind power for propulsion.
sebagai tenaga penggerak,
for months at a time.

why we built it,
alasan kami membuat robot ini,
making its way across the Pacific,
saya berlayar di Samudera Pasifik,
working nonstop,
selama 10 tahun terakhir,
for hundreds of millions of users,
and look at the big picture
dan melihat gambaran yang lebih besar
sangat saya perlukan.
analyzing weather data
menganalisa data cuaca
this beautiful sunset.
matahari terbenam yang indah.
di benak saya:
about our oceans?
tentang laut kita?
saya, sejauh mata memandang,
as far as the eye could see,
kapal kami dengan kuat,
rocking our boat forcefully,
kekuatannya yang belum diketahui.
of its untold power.
about our oceans?
is that we don't know very much.
kita tidak tahu banyak.
how vast oceans are,
betapa luasnya lautan kita,
complex planetary systems
sistem bumi yang kompleks
are mostly invisible to us.
tidak terlihat secara kasat mata.
berdasarkan standar apapun.
accessing lots of sensors --
mengakses banyak sensor --
is scarce and expensive.
sangat jarang dan mahal
a small number of ships and buoys.
sedikit kapal dan pelampung.
was actually a great surprise.
Sebenarnya sangat mengejutkan.
and Atmospheric Administration,
dan Atmosfer Nasional,
200 buoys offshore globally.
digelar di seluruh dunia.
memahami mengapa:
you need a big ship,
diperlukan kapal yang besar,
dalam jumlah besar,
of millions of dollars each,
with a four-mile-long cable
laut dengan kabel sepanjang empat mil
by a set of train wheels,
satu set roda kereta api,
and expensive to maintain.
dan mahal pemeliharaannya.
so much about the big picture
gambar yang lebih besar
of the surface of the ocean.
satu mikron permukaan laut saja.
spatial and temporal resolution,
dan temporal yang relatif buruk,
for cloud cover and land effects
efek tutupan awan dan permukaan tanah
a small cube in the ocean.
secara lebih dekat.
to understand is the surface,
adalah permukaan laut,
if you think about it,
antara udara dan laut.
all energy and gases must flow.
dilewati oleh seluruh energi dan gas.
into the atmosphere.
get dissolved into our oceans.
larut ke dalam lautan.
of all global CO2 gets absorbed.
gas CO2 di dunia dapat diserap.
release oxygen into the atmosphere,
melepaskan oksigen ke atmosfir,
you take comes from the ocean.
yang Anda tarik berasal dari lautan.
penguapan, menjadi awan
which creates clouds
leads to precipitation.
create surface wind,
angin permukaan,
through the atmosphere.
into the deep ocean
of planetary-scale boiler
in short-term events like hurricanes
peristiwa yang cepat seperti angin topan
seperti El Nino
by vertical upwelling currents
oleh arus pembalikan vertikal
which are key in transporting heat
kunci dari pergerakan panas

to marine mammals,
ikan dan mamalia laut,
dan ikan paus.
are mostly invisible to us.

of the walleye pollock,
dari walleye pollock,
you might not recognize,
mungkin tidak Anda kenal,
if you enjoy fish sticks or surimi.
bila Anda suka nugget ikan atau surimi.
but it's actually pollock.
tapi sebenarnya itu ikan pollock.
is the largest fishery in the nation,
perikanan terbesar di sana,
of fish caught every year.

that's used to manage the fishery

pretty good at this repetitive task,

that's pushing the pollock north,

that some of the pieces of the puzzle

Why you should listen
Sebastien de Halleux is currently chief operating officer at Saildrone, a company that designs, manufactures and operates a global fleet of wind- and solar-powered ocean drones monitoring the state of the planet in real time. Saildrone's mission is to quantify planetary systems that affect humanity like extreme weather, global fisheries and carbon fluxes.
Before Saildrone, de Halleux cofounded a video games company called Playfish, which disrupted the industry by turning solitary game play into social experiences. Playfish attracted hundreds of million of users before being acquired by Electronics Arts. He also helped launch one of the very first mobile game companies back when mobiles had black and white screens and actual keypads, which IPOed on NASDAQ.
An internationally recognized leader, recipient of the Tech 100 and Tech Fellow Awards and member of the Aspen Global Leadership Network, de Halleux holds a master's in civil and environmental engineering from Imperial College, London. In his spare time, he spends every minute with his children and friends on his sailboat or driving a mobile cinema truck trough rural Africa. He recently welcomed his fourth child, a daughter named Xochi.
